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

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 :) |

just for the reference, the loop I ran was: while date ; do ./python Lib/test/regrtest.py -v test_multiprocessing ; done |

It's probably a duplicate of http://bugs.python.org/issue8428 It would be nice if you could try to reproduce it with a py3k snapshot though, just to be sure. |

Thanks for reminding me of this issue. I let the same tight loop run on an up-to-date python for a whole day and not stuck happened. |
