I think I've found the code bug causing the leak:

https://github.com/python/cpython/blob/caa331d492acc67d8f4edd16542cebfabbbe1e79/Lib/multiprocessing/pool.py#L180

There is a circular reference between the Pool object, and the self._worker_handler Thread object (and it's also saved in the frame locals for the thread object, which prevents it from being garbage collected).
