as diagnosed by Nick Coghlan. test_capi.py: A test module should never spawn a thread as a side effect of being imported. Because this one did, the segfault one of its thread tests caused didn't occur until a few tests after test_regrtest.py thought test_capi was finished. Repair that. Also join() the thread spawned at the end, so that test_capi is truly finished when regrtest reports that it's done. _testcapimodule.c test_thread_state(): this spawns a couple of non-threading.py threads, passing them a PyObject* argument, but did nothing to ensure that those threads finished before returning. As a result, the PyObject* _could_ (although this was unlikely) get decref'ed out of existence before the threads got around to using it. Added explicit synchronization (via a Python mutex) so that test_thread_state can reliably wait for its spawned threads to finish.
