I'm new to mod_python, but it is documented to be able to do /anything/
that could be a response from Apache.  If the handler were to fetch the
data itself it could write a local file and also return the data to the
client, by calling urlopen() and then read(), write(), and req.write()
repeatedly.  I don't know if the reads and writes will overlap.
