True about mod_perl.  Haven't messed with that myself, either.
fork/exec really is very cheap on Linux, so it's not a huge deal.

I've been playing around with a "native git" cgi thingy the last week
(I call it cgit),  and I've been thinking about adding exactly this
kind of caching to it. And since it's basically a standard git command
written in C, it should have less overhead than any perl
implementation.

Trust me, perl, or CGI, is not the problem.  It's all about I/O traffic 
generated by git.
