Yuck, it would be cleaner to have a dedicated executable for this.  Copy
the file over yourself, launch the program with an Apple event telling it
where you are, and exit.  The program sends MacPerl an event telling it to
run the script and exits.  Really easy stuff if you've already got a
framework for sending and receiving Apple events.  If you simply want to
reexec the script and not actually run two scripts simultaneously, I'd say
this is the way to go.
