I'm familiar with Win32, and the Sleep API function allows optional "defered procedure calls" which are queued and then triggered during sleep; this also wakes it from sleep when done.

I think in principle though sleep is not the right primitive. You want a wait-on-event with an additional timeout. In Win32, I'd use an Event Flag for this. I'm sure any modern OS has a selection of mechanisms like this to choose from.

How to do it portably in Perl? How about a socket? Sleeper does a blocking read on a socket, and signaler writes a byte to signal.
