codecs.StreamReaderWriter seems to delegate everything it doesn't implement
itself to the underlying file instance which is ignorant of the encoding.
The culprit:
def __getattr__(self, name,
getattr=getattr):
""" Inherit all other methods from the underlying stream.
"""
return getattr(self.stream, name)

Note that the xreadlines module hasn't made it into Python 2.4.
