> If some mqtt op blocks on the address or binding manager it will block the
> netty threads and starve existing consumers. In the same way that openwire
> (ARTEMIS-2685) delegates to an ordered executor, mqtt needs to do the same.
> it can leave the ping response in netty to ensure connections stay open while
> busy.
