I've landed a bunch of stuff, and now I am pretty happy. It's also soon going to be weekend, which means family time, so I really hope everyone else is also happy. :-)

A summary of what changed since the initial asyncio checkin:

- Rename the logger to plain "logger".
- Rename Transport.pause/resume to pause_reading/pause_writing.
- Important race condition fix.
- Write flow control for asyncio! (And asyncio/streams.py overhaul.)

And in the tests:

- Make the tests run on Windows.
- Relax various test timeouts to reduce flakiness on slow buildbots.
