(Keyboard)Interupt doesn't get propagated correctly

[donmahallem]

The following will run indefinitely. If an KeyboardInterupt is issued the WebSocket-Transmission will stop but the program will not end. When logging with Verbosity.ALL it will show no further transmission after the first KeyboardInterupt but the whole script won't shutdown.
