Right; ActivePerl doesn't _really_ fork when you use fork, so that example's not going to work for you. I'm pretty sure the pseudo-forked processes they use wouldn't handle signals, even if they were supported under NT, which they aren't :)

This is from the ActivePerl docs, under "Windows Quirks". 

Why doesn't signal handling work on Windows?

Signals are unsupported by the Win32 API. The C 
Runtime provides crude support for signals, but there 
are serious caveats, such as inability to die() or exit() 
from a signal handler. Perl itself does not guarantee that 
signal handlers will not interrupt critical operations such 
as memory allocation, which means signal invocation may 
throw perl internals into disarray. For these reasons, 
signals are unsupported at this time.

Try this script on a Linux box, or, if you're VERY brave, with a native cygwin perl. But be warned, with 5.6.1 under Cygwin, playing with that kind of script causes bad things to happen for me.
