Fallback transport sometimes cut message in half

Question

Originally by -

When testing http://artur.virtuallypreinstalled.com/CardGame/ a couple of times you quite quickly run into a "Communication Error" with a JSON message that abruptly ends in the middle. The server does not support websockets and it seems that the an update to the client some times is pushed in two parts.
