You can use the BrokerClient.poll method to simultaneously poll the queues of multiple Broker clients with a single thread. Unlike the "get events" model, where clients check their queues in serial fashion and block for a specified interval if their queue is empty, the poll method enables an application to dispatch a client to its queue only if there are events there for it to retrieve. This approach results in a more efficient process that wastes fewer cycles on non-productive work (i.e., blocking while a client attempts to retrieve events from an empty queue).

Because the poll method uses a single thread to monitor the queues of multiple clients, it is also easier to implement than spawning individual threads for each client.
