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.
