This is an aspect of Python's singular import hook. imputil is designed
to allow for multiple Importers to be present and to work in harmony. As
long as each Importer can identify that a particular import is part of
its namespace (e.g. HTTPImporter recognizes _http_... as one of its
own), then no conflicts will arise and everything will be hunky-dory.

btw, it might be nice to allow a string to the import statement. I'd
much rather say: import "http://www.lyra.org/greg/python/qp_xml.py"
