kill ALRM, $$ doesn't make sense to me!

It means "send an ALRM signal to the process with PID $$ (which mean the current process). While it may not make much sense in production code, it's certainly useful for testing.

You may want to reread the docs for kill; unlike the shell version, the perl version requires you to have the signal as first parameter, followed by the PIDs you want to send the signal to.
