[Python-Dev] issue 6721 "Locks in python standard library should be sanitized on fork"

I agree that this wouldn't actually benefit anyone.
Besides, I don't think it's even possible to avoid threads in
multiprocessing, given the various constraints. We would have to force
the user to run their main thread in an event loop, and that would be
twisted (tm).

I think this could also be combined with Charles-François' patch.
