[issue45021] Race condition in thread.py

[0x0L]

In the last reproducing example, one can drop the .result() and just submit the task: we're not waiting on any result explicitly. It's the shutdown of the ProcessPoolExecutor that waits forever for the children to exit.

Generally speaking it's probably a bad idea to mix multi-thread and forks. See https://www.linuxprogrammingblog.com/threads-and-fork-think-twice-before-using-them
