文章中的问题我也遇到了，Postcard.timeOut改成小点，就可以修复了，这里的原理是啥， 修改timeOut是否会有问题？是否有更好解决方案？

优化：当Interceptor的process未回调onContinue或者onInterrupt时，框架默认让拦截链继续下去。防止CountDownLatch始终未到0，线程必须等待300s超时，防止线程池等待队列满掉。

文章中提到的将timeout改成小点并没有根本性的解决问题，会导致LogisticsCenter.executor线程池的等待队列会长时间处于满的状态，导致无法接收新的任务，出现不可预测的问题。

核心问题是拦截器的 API 设计的有问题，需要显式调用 onContinue 或者 onInterrupt，否则线程会一直占着

请问大佬们，我在拦截器的process中使用 postcard.setTimeout(2);然而并没有用，点击10次后还是会无效。不知道是不是我的使用方法有问题呢，求解。

点击9次或者5次后拦截器无效对应的是LogisticsCenter.executor核心线程数
拦截器中部分InterceptorCallback未调用 onContinue 或 onInterrupt导致LogisticsCenter.executor无法处理新任务
解决1: setTimeout让LogisticsCenter.executor可以执行新的任务（超时会导致:NavCallback->onInterrupt）
解决2:处理拦截器中未调用 onContinue 或 onInterrupt的InterceptorCallback,不想手动处理页面可以设置setTimeout(1)
