Justin Clark-Casey (justincc) c215b1ad16 If logging a client out due to ack timeout, do this asynchronously rather than synchronously on the outgoing packet loop.
This is the same async behaviour as normal logouts.
This is necessary because the event queue will sleep the thread for 5 seconds on an ack timeout logout as the client isn't around to pick up the final event queue messages.
