Additional information

Looking at https://github.com/nodejs/reliability/issues?q=is%3Aissue%20state%3Aopen%20addons%2Fworker-addon-exit%2Ftest, it seems to be happening since June 6th

It was also reported in #63642 (comment), the PR that introduced this test. Looks like the test failed in that PR (https://ci.nodejs.org/job/node-test-commit-linux-containered/56671/nodes=ubi81_sharedlibs_openssl111fips_x64/console) but it wasn't noticed during review unfortunately

All tests passed.

600k runs without a reproduction 😓 It would be lovely to get a better stack trace here for actually pinpointing where this is coming from. I guess the simplest fix would be to use an async cleanup hook instead of the synchronous one, where the current Environment* isn't required to be on-context, but this does admittedly point to a bit of a usability problem with cleanup hooks in their current form
