> TestDrillbitResilience#cancelWhenQueryIdArrives (previously named cancelBeforeAnyResultsArrive) hangs when the test is run multiple times. 
> -(Will add more information)-
> *Configuration: BIT_SERVER_RPC_THREADS = 1*
> The remote RPC thread with a cancel signal is waiting for the fragment to start accepting external events. The fragment is waiting for a ControlConnection to the Foreman node (through ReconnectingConnection). The Foreman node is waiting for the remote node to accept the connection, which happens through an RPC thread. Distributed deadlock.
> DRILL-3242 should solve this problem.
