question: public synchronized Response deletePriorityTask ( int taskId ) { return highPriorityResponses . remove ( taskId ) ; }
target:  Marks the specified priority request as completed, and returns the suspended Response object for the connection that submitted the priority request (the UI), which probably still waiting to receive a result back over the same connection. A HttpHandler thread can then pump data from the DELETE body back to the origin of the request, without blocking the broker thread. TODO rename to "deregisterSuspendedProducer" and "deregisterSuspendedConsumer" ?
