[issue6721] Locks in python standard library should be sanitized on fork

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Rather than having a kind of global module registry, locks could keep
track of what was the last PID, and reinitialize themselves if it changed.
This is assuming getpid() is fast :-)
