There is a race between creating and adding a DocBroker into the DocBrokers container and cleanupDocBrokers is invoked (on timer) before it had a chance to start its poll thread. This is exceedingly rare, but it has happened. We check that_stop==false flag when deciding isAlive such that cleanDocBrokers will not remove it before its thread had a chance to run (which would happen after adding it and creating the ClientSession). Also, no point in checking isAlive from the polling thread itself (of course it is alive).
