I haven't looked at how OI2's startup is organized, but this is probably
fixable.  Things called from PerlModule or PerlRequire will be run
twice, but modules loaded inside of that will not.

It might not if there is a lot of stuff happening that %INC doesn't know
about.

I still don't understand what you're saying FastCGI does though.
Doesn't it also keep the interpreter alive in memory?

No, it's just a fork.  Forking is very fast on linux and none of the
memory gets copied until the pages are dirty.  FastCGI forks too.
