Somewhere near the top of your cgi script you could put something like the following: 
alarm(180); # stop script after 3 minutes

[download]
Which will kill the cgi script's process (with a SIGALRM) 3 minutes after execution of that line of code.

You could even go as far as printing a warning message if the script is killed this way: 
$SIG{ALRM} = \&sighandler;
 
sub sighandler() {
    print "WARNING: Script timed out or was killed\n";
    exit (0);
}
