A typical message broker system will often be processing multiple requests from the same stream or queue in a parallel, asynchronous manner.
典型的消息代理系统经常将以异步方式处理来自相同流或并行队列的多个请求。

If there are two messages on the queue when ListenerPort1 starts up, the messages will be processed in parallel.
如果在ListenerPort1启动时队列中有两个消息，则这两个消息将并行处理。

Using a dispatcher queue to execute the code in parallel with the caller and then an OS event to block a public method that waits for the result (assuming a synchronous future pattern).
使用一个dispatcher queue来并行的执行调用者和被调用的代码，然后一个操作系统事件会阻塞一个等待结果的公共方法假定一个同步未来模式assuming a synchronous future pattern，看不懂，再汗一个-_- ！
