> The client and broker logs have records of the  message being received by the client
in timely manner (It took 3millisecond to deliver the message). However, the received message
was not put into the client queue and test failed.
> It is unclear at the moment whether it is an issue with threads or a bug in client code.
More investigation is required.
> The issue might cause sporadic timeouts in applications using 0.8...0.91 python API.
