Testing a heroku-specific socket.io performance fix
Reverted commit 5bec95f
Transition to nodejitsu

There's a lot to like about Heroku, but their lack of real websockets support (they

server. That makes re-pairing partners really difficult to do.

I'll use nodejitsu for the time being and check back in on Heroku once they have
