Victor Stinner 13019fdef3 Issue #22117: Add a new _PyTime_FromSeconds() function
Fix also _Py_InitializeEx_Private(): initialize time before initializing
import, import_init() uses the _PyTime API (for thread locks).

Victor Stinner 6aa446cf03 PEP 475: on EINTR, retry the function even if the timeout is equals to zero

* time.sleep()

Victor Stinner 869e1778c0 Issue #22117: Replace usage of _PyTime_ROUND_UP with _PyTime_ROUND_CEILING
All these functions only accept positive timeouts, so this change has no effect
in practice.

Victor Stinner f5faad2bf0 Issue #22117: The thread module uses the new _PyTime_t timestamp API
Add also a new _PyTime_AsMicroseconds() function.

threading.TIMEOUT_MAX is now be smaller: only 292 years instead of 292,271
years on 64-bit system for example. Sorry, your threads will hang a *little
bit* shorter. Call me if you want to ensure that your locks wait longer, I can
share some tricks with you.

Victor Stinner ae58649721 Issue #22043: time.monotonic() is now always available

is compiled in debug mode

fails, don't consume the row (restore it) and fail immediatly (don't call

Skip test_lock_acquire_interruption() and test_rlock_acquire_interruption() of

POSIX condition variable. A POSIX condition variable cannot be interrupted by a
signal (e.g. on Linux, the futex system call is restarted).

  #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.
