Merge current trunk into p3yk. This includes the PyNumber_Index API change, which unfortunately means the errors from the bytes type change somewhat: bytes([300]) still raises a ValueError, but bytes([10**100]) now raises a TypeError (either that, or bytes(1.0) also raises a ValueError -- PyNumber_AsSsize_t() can only raise one type of exception.)

Plug some theoretical insecurities in the test script: - Verify that the SIGALRM handler was actually installed. - Don't call alarm() before the handler is installed. - Move everything that can fail inside the try/finally, so the test cleans up after itself more often. - Try sending all the expected signals in force_test_exit(), not just SIGALRM. Since that was fixed to actually send SIGALRM (instead of invisibly dying with an AttributeError), we've seen that sending SIGALRM alone does not stop this from hanging. - Move the "kill the child" business into the finally clause, so the child doesn't survive test failure to send SIGALRM to other tests later (there are also baffling SIGALRM-related failures in test_socket). - Cancel the alarm in the finally clause -- if the test dies early, we again don't want SIGALRM showing up to confuse a later test. Alas, this still relies on timing luck wrt the spawned script that sends the test signals, but it's hard to see how waiting for seconds can so often be so unlucky. test_threadedsignals: curiously, this test never fails on Tru64, but doesn't normally signal SIGALRM. Anyway, fixed an obvious (but probably inconsequential) logic error. ........ r51234 | tim.peters | 2006-08-12 07:17:41 +0200 (Sat, 12 Aug 2006) | 8 lines Ah, fudge.
