No, I think you're confusing signals with timeouts. When you hook up to a signal, that signal is generated by an external event, and the callback returns a flag saying "I've dealt with this". When you hook up to a timeout, the callback's return is a flag saying "call me again at the next interval".

I think. The documentation on signal callbacks mostly implies they don't return anything!
