> In cluster braindump (when a new member is being added to a cluster) the QueuePolicy is not being serialized out as part of the brain dump.  As a result the newbie cluster can get a mistaken idea of the queue size (in bytes).  
> After many dequeues, the size can go negative, but since the queue size is an unsigned number it wraps around and look like a large positive.  Which sets off the flow-to-disk code, because it thinks that the queue has gotten too large.
> The result:    what():  framing-error: Unexpected command start frame. (qpid/SessionState.cpp:57)
> This fix just adds a little serialization of the QueuePolicy on to the end of the serialization of the Queue.
