For things like mod_wsgi and uwsgi, we're not actually implementing
the transport or protocol inside of Python at all - its all happening
in C and often in an entirely separate process.

I think it's entirely reasonable to want to write
middleware/frameworks in that context using asyncio, and today there
isn't a defined protocol for doing that.
