Amaury Forgeot d'Arc 1f40c8a8d7 #Issue3088 in-progress: Race condition with instances of classes derived from threading.local: ...

When a thread touches such an object for the first time, a new thread-local __dict__ is created,
and the __init__ method is run.
But a thread switch can occur here; if the other thread touches the same object, it installs another
__dict__; when the first thread resumes, it updates the dictionary of the second...

This is the deep cause of the failures in test_multiprocessing involving "managers" objects.

Also a 2.5 backport candidate.
