  There are tons of different ways to do this.  I would suggest
  looking into the different ways to do RPC with Perl for your
  operating system or use the database itself to communicate
  between the two processes.  

  There isn't much inside of Apache or mod_perl that will help
  you with this, but just because you are in an Apache/mod_perl
  environment doesn't mean you can't use the standard Perl tools.
