Have you looked at CGI::Fast ? It permits persistence like mod_perl,
but is easier to set up and configure.
I've just begun playing with it myself for caching the DB hash for a
Perl-based online game, but it's doing well so far.
For you, CGI::Fast should allow you to keep the dictionary in memory
between invocations.
Another technique I've used is to run the C program as a daemon process,
and then connect to it through a socket from your perl program when you
need to do operations. But that's probably overkill for your case...
