I'm also rather surprise about those MANY incompatibilities that haven't
been discussed and shall silently be accepted. Right now I am aware of
three problems:

- WSGI disallows response streams
- Twisted handles chunked requests differently (zsync checkin breaks)
- ZEO is broken or at least suboptimal

This makes me pretty nervous about our development process / decision
making.

Cheers,
Christian
