仔细分析了下，一个可能的原因： 由于priority_to_run在提交任务时并没有发送signal给其他在waiting状态的worker。 同时bthread的attr是传递的属性，导致epoll thread创建子thread也具有BTHREAD_GLOBAL_PRIORITY，priority_queue中会有多个task。极端情况下，只有一个worker在工作，其他在sleeping，这个工作的worker在执行完priority queue中的epoll task的前一个task后进去wating状态，导致再也没有worker工作。系统进入假死状态。 -- This is an automated message from the Apache Git Service.
