> When producer-flow-control throttles a producer, the entire connection for the client, or network bridge, can be blocked until space clears.
> A unit test will be attached that demonstrates this situation with any of the following types of messaging:
> * PERSISTENT, transacted
> * NON-PERSISTENT, non-transacted
> * NON-PERSISTENT, transacted
> PERSISTENT, non-transacted messages don't have this problem.  Internally, it seems that any time messages are sent asynchronously across the transport (i.e. isResponseRequired() == false), the problem occurs.
> The expected operation is for producers to the destination to block on send() and all other operations across the same connection to continue normally.
