Mmm, this is unsafe: if yet another signal arrives between the setjmp return and locking ss, it will be processed instead of being blocked. I know from experience that sigwait is a pain to implement correctly, especially with threads with global signals, since you're supposed to either deliver the global signal to some thread which doesn't block it, or wake a thread which is waiting for it in sigwait...
