> ProducerFlowControlTest#testSendTimeout test fails sprodically on 0-10 profiles.  
> The test is racey.  The test relies on message n-1 causing flow control to be imposed
before the test can try to send message n.  If flow control is not imposed before the client
tries to send message n, the test will fail.  In the failing case the client has not processed
the incoming MessageStop before it sends message n.   The test tries tries to prevent this
by sync'ing twice.  This approach is ineffective for 0-10 as the send sync to optimised out
and does not caused an ExecutionSync.
> The test issue does not affect the usefulness of the feature itself.
