New submission from Sandro Tosi <[email protected]>:
Hello,
when trying to see if issue6661 was still valid, I run test_multiprocessing in
a tight loop and I got it reproducibly stuck on test_make_pool:
...
test_imap_unordered (test.test_multiprocessing.WithManagerTestPool) ... ok
test_make_pool (test.test_multiprocessing.WithManagerTestPool) ...
when I enter Ctrl+C here's the traceback (on 2.7 HEAD):
test_make_pool (test.test_multiprocessing.WithManagerTestPool) ... ^CProcess
PoolWorker-5:3:

test_multiprocessing
It's reproducible here so I can make any tests you want to verify the problem
(I don't know what to look at, sorry); just to give some more info, here's a
Debian sid on AMD64.
Cheers,
Sandro
PS: it's my first bug report to python, so please be gentle and forgive any
mistakes I could have made :)
