i woke up this morning and had a moment of clarity. (thanks for /msging me the link here.) you need to reload the signal handler for it to work again. try this:

#!/usr/local/bin/perl -w
use strict;
$|++;

{                                 # global count, closure
    my $count=0;                  # initialize count
    sub inc_count { ++$count }    # increment count
    sub get_count { $count }      # get count
}

$SIG{INT} = \&_SIGINT_;           # set signal handler (CTRL-C)
sub _SIGINT_ 
{                                 # handle CTRL-C
    inc_count();                  # increment global count
    $SIG{INT} = \&_SIGINT_;       # reset signal handler (CTRL-C)
};

while(1)
{                                 # infinite loop
    my $count = get_count();      # get the count of CTRL-C's
    $count % 2                    # branch (just to do something)
        ? printf "\b\b\b\b\b\b\b\byes   %2d",$count
        : printf "\b\b\b\b\b\b\b\b   no %2d",$count;
    sleep 1;                      # take a cat nap
    $count >= 10 and last;        # break loop (not so infinite)
}
print "\ndone!\n";                # et voila!

</code> oh, and by the way, if you're running your code on windows, note that kill won't work as you think. specifically, kill will *always* abort the program, and force the exit code to the number you send. it will not send a signal to the program, like it does on unix.
