You can drop it if you want, but I just don't know how long it will
take for me to finish the bootstrap work (for instance I am having to
rewrite the warnings module in C). So there is a chance it might still
be useful, but I can't guarantee it.

I use the imp module to handle the actual loading, but the importers
and loaders are all in Python. You can see the implementation in the
sandbox under import_in_py.
