My guess is that, even though you're using yield, something
is buffering the response anyway. Do you have
stream_response = True as described at http://ww
w.cherrypy.org/wiki/ReturnVsYield? Even if you do,
perhaps there's a filter or something that's buffering? Add
a line to _cpwsgi.py (round about line 90) and see if
response.body is a generator or not.
