The main reason for setting heartbeat is to fail the client from one
node of the cluster to another faster + have the broker 'release' any
resources fro re-use associated with that session, for example
'exclusive' queues.
In connection settings:
uint16_t heartbeat;
/**
* The maximum number of channels that the client will request for
* use on this connection.
*/

Hmm...so what will happen if I don't set it? In the c++ API doc from redhat,
there's nowhere mentioning this heartbeat, I only get this from the qpid FAQ. I
tested the cluster by cleanly shutdown one broker while producing a lot of
messages to a queue, the other broker still works fine and no messages were
lost.

I haven't set any heartbeat in ConnectionSettings explicitly, the cluster
worked most of the time, so I guess the default heartbeat interval is fine.
By default heartbeats are not used for the c++ client. You must set the
interval in ConnectionSettings to turn them on.
