So maybe it makes sense to put something into the standard library that everyone could contribute to and use. With regard to forking -- is there another way? I don't have the expertise to have any idea if this is possible, but: start up python capture the entire runtime image as a single binary blob. could that blob be simply loaded into memory and run? (hmm -- probably not -- memory addresses would be hard-coded then, yes?) or is memory virtualized enough these days?

You might want to look into combining this with PyRun:

which takes care of mmap'ing the byte code of the stdlib into memory.
