That's pretty cool. :)
I think people will be a bit confused about the relationship between
this and repoze.zope2, though. Maybe we can make a statement about how
they differ and whether they ought to be consolidated?
As for IStreamIterator, I think it should work to just return the
iterator as the WSGI body iterator. At least that works in repoze.zope2.

That's really awesome!

Are there any cases other than IStreamIteartor in that case?
