With this arrangement, even if Thread B has modified the top while Thread a tries to pop, you're sure that no elements in the stack are skipped.

这样，即使线程b在线程A试图弹出数据的同时修改了堆栈顶，也可以确保不会跳过堆栈中的元素。

Because the TimerCallback function gets called on a worker thread, there are no skipped beats (assuming the availability of worker threads).

因为TimerCallback功能也是在工作者线程上被调用，没有一个跳动被跳过(假设有工作者线程可用)。

Skipped 31 frames! The application may be doing too much work on its main thread.

这个不一定是你程序的问题，只是说可能是主线程的工作太多而已。
