Research direction

Start by reading and running testmpdaemon.py, the linked bug-demo code, to reproduce the multiprocessing behavior and compare it with threading. The issue does not define the intended behavior or identify CPython implementation files, so completion would require agreeing on semantics and adding regression coverage.
