Hi there,
If the calling process has SIGALRM blocked, timeout simply never times out.
Find attached a small program to demonstrate the problem and a patch to
fix it by unblocking the necessary signal (at least on x86/linux).
If this is intended behavior, I would suggest to document it explicitly
to prevent people from tapping into the same pitfall that I hit.
Greetings
Stephan
