New submission from shani:

Multiprocessing pool.py gets SimpleQueue objects as inqueue and outqueue.
when it terminates, it doesn't call the close() method of the queues' readers and writers.
As a results, 4 file pipes leak in one pool termination.

Expected: The pool closes reader and writer pipes of the inqueue and outqueue when it terminates.
What did happen: the pool doesn't close the pipes. 4 pipes leak.
