Thanks. Unfortunately the perl program is not asleep waiting for the signal, it is doing other things. I thought I could fork off a process inside the perl program that would sleep until there is something to read, but it seems like it will be problematic having that process asynchronously tell the parent process to jump into the handler loop. Perhaps not?

Thanks!
