reinitializing Perl's notion of $$ in mod_perl

[Mark Blackman]

While I did find Torsten Förtsch's very useful Perl::AfterFork  
module, surely the
mod_perl code must be doing something like this itself, no?
I'd be grateful to understand mod_perl's response to Perl's
pid caching is, given that forking *will* happen in the mod_perl
environment.
