[New-bugs-announce] [issue14976] Queue.PriorityQueue() is not interrupt safe

[Johan Aires Rastén]

New submission from Johan Aires Rastén <johan at oljud.se>:

Python 2.7.3 (default, Apr 20 2012, 22:39:59) 
[GCC 4.6.3] on linux2

If a signal handler calls Queue.PriorityQueue.put and a second signal is received while one is already being processed, neither of the calls to put will terminate.

Highly dependent on timing so it might be difficult to reproduce.
