6161,twisted.internet.test.test_sigchld way too aggressive in assuming no previous fd or SIGCHLD handler was installed,itamar,itamar,"`twisted.internet.test.test_sigchld.SetWakeupSIGCHLDTests.setUp` assumes no one has previously set a SIGCHLD handler or registered a wakeup fd. If someone has, that is considered an error. However, any random test that uses the reactor will cause this registration; AFAICT this never caused problems before due to a specific sort order of running tests.
