我再补充下场景描述,对于一个线性变化的状态机来说,如果中间某个状态流转足够快(比如直接 return),那么通过线程池异步 fire 对应的 event 可能与上一个 event 近乎同时进入 queuedEvents

如下图所示,两个线程,其中一个刚好执行到 processEvents 中 data.read.currentRawState() 位置(持有写锁,标记 status 为 busy,e1 进入 queuedEvents),另一个刚刚提交 e2 进入 queuedEvents 并进入 processEvents 方法,那么两个线程都从 processEvents 方法返回后,queuedEvents 中还会存留一个 e2,如果后续不再有新的 event 进入队列,触发 processEvents(),则这个 e2 就不再会被处理,造成状态机状态流转卡住的现象
