Maintaining a pool of Perl interpreters

[Jeremy Redburn]

I am looking for an example of maintaining a persistent pool of Perl 
interpreters for use from my C program. I've looked through the mod_perl 
source code, but am a bit overwhelmed and as far as I can tell it seems 
to maintain a single interpreter per Apache process. If anyone has any 
advice or a pointer to examples, it will be greatly appreciated.

Thanks much,
Jeremy
