Eeek. Any idea how that happened? Presumably, thread control in a WSGI 
scenario would be up to the WSGI web server, not Zope 2.

I implemented IStreamIterator support in repoze.zope2; it's actually 
pretty easy, since a stream iterator is an iterable, just like a WSGI 
response. I think you can just chuck it back. The only thing to watch 
out for is that you don't accidentally unwind it anywhere.

I think testing with the Paste server is probably the best idea.
