            Assignee: Zhuo Liu
             Fix For: 1.0.0, 2.0.0


The current exception handling in WorkerBackpressureThread can cause the thread to die before we want, causing potential backpressure flag synchronizing problem. 
Also, we need to cleanup the topology backpressure directory during killing.
