I don't know of techniques which aren't Windows specific.  Greg??
Gordon??

I don't think so.  It adds to the list of available compiled-in
modules, so that were they imported, they would be available for import.
But the problem is how to get them imported.  In particular, "__main__"
would never be called unless it were explicitly a frozen module.  The
list of frozen modules PyImport_FrozenModules is not the same as
PyImport_Inittab.  Actually, I am not sure how to solve this even
in my current code, except in a Windows-specific way.
