#242 closed protocol defect (fixed)

Wait for acknowledgement before sending new notification

Section 4.5

When a server is in the process of delivering a confirmable notification and is waiting for an acknowledgement, and it wants to notify the client of a state change using a new confirmable message, it MUST stop retransmitting the old notification and SHOULD attempt to deliver the new notification with the number of attempts remaining from the old notification.

Cullen Jennings pointed out that the server must not start transmitting the new notification immediately, but wait for the current attempt to time out or succeed. If the resource changes its state multiple times before then, only the last one is transmitted.
