> Imagine two threads... producer/consumer...
> If the server crashes when both ACK and send are still coming back from the execution (at the same time)... there is a chance of creating a message.
> I have created MultiThreadFailoverTest::testFailureOnSendReceiveSynchronized for this... But I have seen testMultiThreadFailover failing ocasionally.
> testFailureOnSendReceiveSynchronized poisons the server is a special way to cause the synchronization issue in a predictable way.
