Re: [hybi] Clarify the role of closing handshake

Okay, I admit my example was bad.

Just to be clear, even with this code:

      websocket.send("a-message-needs-to-reach-server")
      websocket.close()

>From your opinions, programmers should not expect that the message always 
reach the server. (granted)

Now, here's another question for you.

If onclose() callback is made on the websocket, would it be helpful if 
that callback (with wasClean=true) guarantees
that the message has been delivered to the server?

# trying to figure out whether graceful shutdown at least during 'closing' 
state would ever be helpful.

Thanks,
