The problem can be simplified to this:

py> import xml.sax,xmlcore.sax,sys
py> sys.modules['xml.sax'] is sys.modules['xmlcore.sax']
False

One way to fix this would be to never refer to "xmlcore"
explicitly (i.e. import from xml.sax._exceptions in
expatreader), but I guess that would defeat the purpose
of the xmlcore renaming.
