Don't kill the program (e.g. by sending SIGINT to the program) and then complain that the rest of the program (e.g. the signal handler) doesn't run.

I didn't.

$ perl -e 'sleep 10;print"World\n"' | perl -e '$x=time;
    $SIG{ALRM}=sub{print"Hello ";$y=time}; alarm 2;
    $z=<>; print $z,$y-$x," ",time-$x,"\n"'
Hello World
2 10

On my system, all of the above output does not happen until after 10 seconds. See above.
