The multiprocess/pool.py distributed with the Python 2.7.2 Windows Installer is different from the one distributed with the 64 bit windows installer or source tarball - and is buggy.
Specifically, see Pool._terminate_pool:
def _terminate_pool(cls, taskqueue, inqueue, outqueue, pool,
worker_handler, task_handler, result_handler, cache):
# this is guaranteed to only be called once
debug('finalizing pool')
worker_handler._state = TERMINATE
task_handler._state = TERMINATE
taskqueue.put(None) # THIS LINE MISSING!
Without that line, termination may deadlock during Pool._help_stuff_finish. The consequence to the user is the interpreter not shutting down. |
