| The test added for issue #30703 crashes on some Unix buildbots (FreeBSD 9.x, OS X Tiger, AIX). Example here: http://buildbot.python.org/all/builders/AMD64%20FreeBSD%209.x%203.x/builds/275/steps/test/logs/stdio As noted in the PR for that issue, some systems may have low resolution for setitimer(). For example, the FreeBSD man page says: > Time values smaller than the resolution of the system clock are rounded up to this resolution (typically 10 milliseconds). |

| Hmm, that function only sends 20 signals in a row. How can it timeout after 15 seconds? |

| Ok, there's definitely something fishy here. Look at the elapsed times: 0:16:33 load avg: 0.93 [281/406] test_ossaudiodev skipped -- running: test_signal (874 sec) test_ossaudiodev skipped -- [Errno 2] No such file or directory: '/dev/dsp' 0:16:59 load avg: 0.95 [282/406/1] test_signal crashed (Exit code 1) Timeout (0:15:00)! faulthandler claims that 15 minutes have elapsed, but only 59-33 = 26 *seconds* have! |
