What steps will reproduce the bug?

Examples in our CI:

• https://github.com/vitest-dev/vitest/runs/7704223380?check_suite_focus=true
• https://github.com/vitest-dev/vitest/runs/7685754161?check_suite_focus=true

After all tests are done, we are getting the error:

Assertion failed: (napi_create_external(env, fseenv, fse_environment_destroy, NULL, &result) == napi_ok), function fse_environment_create, file ../src/fsevents.c, line 87

I wasn't able to find this file in Node repo.

We are also getting Empty MaybeLocal error sometimes, which might be connected:

• https://github.com/vitest-dev/vitest/runs/7685755871?check_suite_focus=true
• https://github.com/vitest-dev/vitest/runs/7685757762?check_suite_focus=true

I am not able to reproduce it on smaller scale for now, unfortunately. It seems, there is some kind of race condition.

Code that fires up workers:

• https://github.com/vitest-dev/vitest/blob/95c1d34368d799da417da219d394545ee83164e2/packages/vitest/src/node/pool.ts#L96

You can also notice that errors happen with "close with time out", this code is triggered here:

• https://github.com/vitest-dev/vitest/blob/95c1d34368d799da417da219d394545ee83164e2/packages/vitest/src/node/core.ts#L436

I am able to reproduce it almost consistently in Vitest core tests:

• Download Vitest repo (only node/reproduce branch is needed)
• run

pnpm install
cd test/core
ppm run test

If you comment out this.pool?.close() (which is an async noop), you should see error less time. But I got a new error with it:

Run it a few times, if you don't see an error.

If I comment out this.close entirely, I get this error:

If I call pool.destroy() inside pool.close, I also get the error quite often:

What do you see instead?

I wasn't able to find this file in Node repo.

It looks like this is from fsevents?

FSReqPromise errors

These may be fixed by #42910, which will be in Node.js v16.17.0. But I'm not sure.

Based on previous issues, it feels likely the race here is between the shutdown & the other actions trying to call into Javascript.
