 * macrotask — two coalescing turns later, even for a call made on this very
 * thread. `Context.destroy()` then runs the threadsafe function's cleanup hook,
 * which drains the queue with a null env and *discards* whatever is still in it.
 *
 * So destroying without yielding first strands exactly the promises the barrier
 * exists to settle. Yield real event-loop turns until the addon reports the
 * queue empty; microtask checkpoints cannot help, no number of them lets a
 * macrotask run.
 *
 * Returns nothing when there is nothing to wait for, which keeps disposal
 * synchronous in the common case.
 *
 * The "already drained" flag is set only once a wait has actually finished.
 * Scheduling a macrotask can fail — a host-provided or patched `setImmediate`
 * that throws is enough — and a disposal that rejects stays retryable, so
 * marking the drain complete up front would make the retry skip it and destroy
 * the context with the barrier's settlements still queued.
 *
 * A wait that runs out of turns with the counter still nonzero rejects with
 * `ERR_NAPI_WASI_CLEANUP_PENDING` for the same reason: at that point
 * "finished" is indistinguishable from the stranding above, and destroying
 * would discard the very settlement the wait was for. The rejection leaves the
 * flag unset and disposal retryable.

/**
 * Settles this addon's outstanding `napi_async_work` before the teardown that
 * would strand it.
 *
 * `napi_prepare_wasm_env_cleanup` does not cover async work, and nothing about
 * it is observable from JavaScript: the threadless archive resolves
 * `napi_*_async_work` through the `@emnapi/core` plugins, but the threaded one
 * links the C `async_work.c` on the uv threadpool, so there the wasm neither
 * imports nor exports those symbols and the only brackets a loader could watch
 * (`_emnapi_ctx_*_waiting_request_counter`) are shared with threadsafe
 * functions. The addon is the one place both flavors go through, so it answers
 * for both, through the same kind of handshake the settlement drain uses:
 *
 *   - `napi_wasm_cancel_pending_async_work()` cancels what no thread has
 *     started. Those completion callbacks run with `napi_cancelled`, which
 *     napi-rs turns into a promise rejected with an `AbortError`.
 *   - `napi_wasm_async_work_pending()` counts what is still owed a completion
 *     callback. Work already executing refuses cancellation and stays counted
 *     until it finishes normally — which it can, because this runs before the
 *     barrier, before `Context.destroy()` and before anything is terminated.
 *
 * Both exports are optional: an addon built against a napi crate that predates
 * them drains nothing and keeps the previous behavior, exactly as the
 * `napi_wasm_env_cleanup_pending` handshake degrades.
 *
 * Returns nothing when there is nothing outstanding, which keeps disposal
 * synchronous in the common case. The promise it returns otherwise never
 * rejects.
 *
 * The wait has no deadline, and that is the point: giving up would destroy the
 * environment with a completion callback still owed, which is the stranding
 * this exists to prevent. A task whose `execute` never returns already keeps an
 * *undisposed* process alive in exactly the same way, so disposal inherits that
 * rather than inventing a bound it cannot honor.
 *
 * Safe to call from inside a completion callback, which is reachable: settling
 * a task runs addon code that can re-enter JavaScript — a setter on the value
 * being handed back, a threadsafe-function callback — and that JavaScript can
 * call `dispose()`. Two things make it terminate rather than wait on itself:
 *
 *   - The addon keeps a work registered until its completion callback
 *     *finishes*, so the count read here is at least one and this takes the
 *     polling path instead of declaring the environment drained and tearing it
 *     down from inside the frame that is still settling a promise.
 *   - The poll is a timer, so it cannot run until the callback has returned to
 *     the host — by which time that work has left the registry. The count the
 *     next poll reads is the one taken after the callback finished.
 *
 * `__disposeWasiBinding` hands every caller the same in-flight promise, so the
 * nested call joins this disposal rather than starting a second one.

 * Initialization can fail *after* registration has already run, and registration

 * JavaScript. The barrier cancels that work and *queues* the settlement, so this
 * path needs the same drain the ordinary disposal does — destroying without
 * yielding discards the queue with a null env and strands the promise.
 *
 * Stays synchronous when nothing is queued, which covers every failure before
 * `beforeInit`: there is no instance to run the barrier on, so nothing to drain.
 *
 * A barrier or drain that did *not* finish stops the rollback short of
 * destroying, which is what `dispose()` already does — a rejected drain there
 * never reaches `__continueWasiDisposal`. Destroying anyway is the worse of the
 * two trades, and not because of what it saves:
 *
 *   - It cannot deliver the settlements. `Context.destroy()` runs the
 *     threadsafe function's cleanup hook, which drains the queue with a null env
 *     and discards it, so a promise that already escaped into JavaScript hangs
 *     forever with nothing left that could ever settle it.
 *   - It saves less than it looks. `Context.destroy()` stops JavaScript calls
 *     and runs cleanup hooks; it does not free the wasm instance or its Memory,
 *     which this module's scope holds either way. What stopping short retains is
 *     the emnapi context's bookkeeping and its un-run cleanup hooks.
 *   - Retry is not theoretical. A rollback that records a cleanup error is
 *     already kept in the process-wide registry above, so re-`require()`ing this
 *     file replays it instead of re-instantiating — and the `6e15de6f` flag fix
 *     means the replay drains again rather than skipping it. Destroying first is
 *     what makes that retained record useless.
 *
 * The residual cost is honest: the CJS flavor hands the context to its
 * `process.on('exit')` teardown, so a process that never retries still reclaims
 * it on the way out. The ESM browser flavor has no equivalent — a module that
 * throws while evaluating is permanently errored, so re-importing rethrows
 * without re-running this file — and there the context stays until the realm
 * goes away. That is the deliberate choice: a hung promise is a silent liveness
 * bug with no upper bound, while the retained bookkeeping is bounded by the page.
