可以阻塞线程，再调用f.get()可以让网络调用继续进行或是忽略掉f。

allows your thread to block - by calling f.get() - to ensure the network calls succeed, or go away by ignoring f altogether.

Let's go the other direction. And yes, I guess I'd better say s not 2, or we're going to get an error here. Again, in twenty-three checks.

这里我得说不能是2，否则要报错了，再一次，调用了23次,在这个例子里，它从尾部开始。
