We shouldn't be implementing a WSGI server *at all*. The fact that one 
cannot run Nova inside a true WSGI server (i.e. Apache/mod_wsgi, uwsgi, 
etc) is a bad thing.

For the record, I'm very much in favor of the approach Chris has taken 
in a framework-less implementation with nothing other than the (tiny) 
selector library as a dependency. I'd like to see the work move forward.
