Greg Brockman <g...@ksplice.com> added the comment: For what it's worth, I think I have a simpler reproducer of this issue. Using freshly-compiled python-from-trunk (as well as multiprocessing-from-trunk), I get tracebacks from the following about 30% of the time:
""" import multiprocessing, time def foo(x): time.sleep(3) multiprocessing.Pool(1).apply(foo, [1]) """ My tracebacks are of the form: """ Exception in thread Thread-1 (most likely raised during interpreter shutdown): Traceback (most recent call last): File "/usr/local/lib/python2.7/threading.py", line 530, in __bootstrap_inner File "/usr/local/lib/python2.7/threading.py", line 483, in run File "/usr/local/lib/python2.7/multiprocessing/pool.py", line 272, in _handle_workers <type 'exceptions.TypeError'>: 'NoneType' object is not callable """ ---------- nosy: +gdb _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4106> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
