This code hangs: """ executor = concurrent.futures.ProcessPoolExecutor(2) executor.map(is_prime, [1, 2]) executor.shutdown() """ while this doesn't: """ executor = concurrent.futures.ProcessPoolExecutor(2) executor.map(is_prime, [1, 2]) time.sleep(1) executor.shutdown() """ ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12456> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
