Here is another theory to explain the hang: When sigwaitinfo() is being called, and the SIGALRM signal arrives, it executes the signal handler (both the C handler and later the Python handler). If the SIGUSR1 signal arrives while either of these signal handlers are executing, it will be missed, and when sigwaitinfo() resumes it will hang. This would also be avoided by blocking SIGUSR1.

I wonder why the hang only seems to happen with BSD though.
