Flask has this awesome little thing called the request context, which
is the reason things like "request" and "g" work the way they do. Sure,
it's a ton of magic, but it's usefull. Unless you use websockets and need
an ongoing loop. This function HAS to exit for socketio to parse NEW
emissions from the client, so we start a greenlet attached too the socket
(when the socket dies, the greenlet will too), and pass it the WS/user.
