Actually there's some Jython-specific code in xml/sax/__init__.py. Two
places, both questionable. One of them refers to sys.registry. The other
appears to be a workaround for Jython not having 4-argument __import__.

Yes, it can be solved that way: Jython could implement pyexpat. I don't
know just how crazy that idea is; my impression is that it could be done,
perhaps imperfectly, as a wrapper around SAX.
