Forgot: The signal trampoline is pretty weird. The threads library signal masking to get around the non-restart of signals that was brought into BSD with POSIX (the default used to be signal restart) causes problems. There's a guy who is having trouble with a siglongjmp() out of a signal handler when using threads, right now. I guess he doesn't understand that the thread that gets the signal and does the siglongjmp() is not necessarily the thread that did the original setjmp()...
