While we're iterating over the queues in ReplyWaiters.wake_all(), new queues can be registered and we get: RuntimeError: dictionary changed size during iteration Instead of using an iterator, take a snapshot list of message IDs and operate on that. We don't actually care about any new queues added after wake_all() is called because the connection lock has already been dropped so one of the other waiters must have picked it up. We also don't need to worry about queues being removed - if we write to a removed queue, that's not going to be a problem. Change-Id: Ib572cbfd3a7346b76579f82b64aa85a03c1a4fb2
