@chenBright @zhengJade 有没有可能是下面这段代码的一致性导致的问题呢：
```
while (g->_last_context_remained) {
RemainedFn fn = g->_last_context_remained;
g->_last_context_remained = NULL;
fn(g->_last_context_remained_arg);
g = BAIDU_GET_VOLATILE_THREAD_LOCAL(tls_task_group);
}
```
如果当前线程的TaskGroup::_last_context_remained（这时候是priority_to_run）在别的线程被运行过，但因为一致性问题导致当前线程会错误的运行priority_to_run,这样就有一个额外的task变成priority
task。如果这个task刚好排在epoll前面，就有可能导致大家都饿死
