Robert's comparison with mod_perl is very apt. Preloading code gives dramatic performance gains in production situations where there's a significant codebase and connections are frequent. The docs for plperl.on_perl_init could include a section relating to it's use with shared_preload_libraries. That could document any issues and caveats you feel are important.
