Victor Stinner 754851f456 Issue #11223: Add threading._info() function providing informations about the
thread implementation.

Skip test_lock_acquire_interruption() and test_rlock_acquire_interruption() of
test_threadsignals if a thread lock is implemented using a POSIX mutex and a
POSIX condition variable. A POSIX condition variable cannot be interrupted by a
signal (e.g. on Linux, the futex system call is restarted).

Antoine Pitrou 7c3e577395 Issue #7316: the acquire() method of lock objects in the :mod:`threading`
module now takes an optional timeout argument in seconds.  Timeout support
relies on the system threading library, so as to avoid a semi-busy wait
loop.

  #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.
