There was a problem hiding this comment.
I personally support hard compatibility with CPython.
At least, leaving comments about CPython implementations for each places will be helpful for future workers.

Whatever it is it isn't reproducible, as threads tend to be. Locally it once started spinning on |

I’ll take another look. The problem is that fork enables functions like os.spawn which in turn enable a whole bunch of new tests. |

thanks! This is superseded by #4877 if I'm not mistaken. Feel free to re-open if I'm mistaken. |

This seems to work and tests pass (
test_posix:test_register_at_fork).I took a look at CPython's implementation and it seems they're doing more things before/after fork, namely acquiring the import lock, and re-initiating the interpreter in the child process (see here - https://github.com/python/cpython/blob/main/Modules/posixmodule.c#L593). Do we want to do the same thing here?
