I was composing this perl poem and I ran into a strange issue with the kill command. I've only used it once before (Perl 5.10.0 on Ubuntu) and it worked fine, but this time, every time I try to kill ALRM, $$, the program quits. I tried kill 14, $$, same issue. I had set a signal handler for SIGALRM:

$SIG{ALRM} = sub {
   print "Alarming!\n";
};

...but it doesn't print. Any guesses as to what's going on here?

> perl -MConfig -e "print $Config{sig_name}"
ZERO HUP INT QUIT ILL NUM05 NUM06 NUM07 FPE KILL NUM10 SEGV NUM12 PIPE
