Perhaps, but the handy things supervise does (like redirect file
descriptors) would be more of a hindrance than a help here, so it
would probably be much easier to wrap your script in another Perl
script that did something like:

  while(1) {
    system("/path/to/real/program");
  }

That's still not perfect; a better solution would patch Apache to
restart the program (as Charlie suggests), or else to send requests
over a socket, which could be listened to by a supervised daemon.

Good luck!
