You can just call "import" on the modules rather than "use", but that doesn't gain you a whole lot. > > (At the cost of having them (insibly) duplicated in all the children > > processes). > Again, this is the first time this is mentioned.

Preloading avoids the duplication (at least as far as copy-on-write allows). "use"ing multiple times doesn't load multiple copies, it just imports the symbols to the local namespace. I'm not sure what led Andre to believe otherwise. (Andre, can you explain?)
