Juliusz Chroboczek fc9bbf20ea Don't close writer channel at client shutdown. 
Closing the channel could cause a panic if a c.write was pending.
Instead, ensure we send a closeMessage to the writer, and cause the
writer to exit when it receives a closeMessage.

the protocol for joining multiple groups (think federation).
