RE: issue 11 -- window size

Is there really a point of reserving.  I mean, what's the peer going to do

The peer will silently drop it until it's finished with another one, right.
So what !  I can just keep transmitting my mobike message(s) until the peer
has a chance to process it and respond, right?
