> If a federated link is established to a source broker that is slow to respond with the
AMQP handshake, the destination broker cluster will shutdown with an "Unknown connection"
error.  
> Exception constructed: Unknown connection: Frame[BEbe; channel=0; {ClusterConnectionDeliverDoOutputBody:
limit=2048; }] control 2.0.0.0:22138-14 (qpid/cluster/Cluster.cpp:542)
> Steps to Reproduce:
> 1. Configure a clustered broker
> 2. Start netcat in listen mode (nc -l 6000)
> 3. Add a route between the clustered broker and nc (qpid-route queue add localhost:5672
localhost:6000 amq.fanout foo)
> 4. Clustered broker shuts down
