[issue13373] Unexpected blocking call to multiprocessing.Queue.get with a timeout
report at bugs.python.org

New submission from Arnaud Ysmal <stacktic at netbsd.org>:
Using get(timeout=1) on a multiprocessing.Queue sometimes leads to a blocking get.
It seems that there is no check whether the timeout has expired after acquiring the lock but before the time.time(), which can cause a call to poll() with a negative timeout.
