I have a servlet that flush()es it's response in order to show progress. I
notice that if an exception occurs during the process, instead of getting
the normal Python exception page, I get yet another exception:
Traceback (most recent call last):

At some point, we'll need more sophisticated handling. Like maybe the
exception handler could check if the response is committed and if so, only
display exception information if the content/type is HTML.
(This is on Linux, Apache 1.3.x, Webware CVS, mod_webkit)
