We're stuck with globals for that. The only argument a handler gets is the name of the signal that fired it.

Since we don't know where in the code a handler will fire, only global variables can be relied on to be visible to the handler. It's best if they are not file-level lexicals. That produces a closure with the handlers which use them, occasionally producing hard-to-debug "features".

Added: The first section of your local perlipc is on signal handling, and is full of great tips and tricks.
