Bzzzt! That should read: 
my $PID = fork();
if ($PID) {
    # in the parent process
}
else {
    # in either the child process or the parent
    # process, depending on whether the fork()
    # succeeded or failed.
}

Always, always, always check the return values of your system calls. And that includes fork.

    Absolutely correct. I will now punish myself as all devout monks should do:

    Bad programmer,... sloppy code!..... sloppy code!... Bad!!

    I will now force myself to code in PHP for the next 2 weeks as further punishment for my sins.

    (I forget sometimes how dangerous simplifications are in the context of fork.)
