> The lock ordering leaves open the possibility of a deadlock if one thread is
> fetching on a receiver, another is accepting messages received by it and a
> third is closing the receiver.
> Thread 1 holds SessionImpl's lock and is blocked on IncomingMessage's lock.
> Thread 2 holds IncomingMessage's lock and is blocked on ReceiverImpl's lock.
> Thread 3 holds the ReceiverImpl's lock and is blocked on SessionImpl's lock.
