While spin locks are CPU-intensive and appear inefficient, they can be more efficient than suspending the thread and subsequently waking it up if the lock in question is held for a very short time.

虽然旋转锁是cpu密集型的，显得效率低下，但是如果争夺的锁被持有的时间非常短，那么旋转锁要比暂挂线程然后再唤醒它更有效率。

In short, each thread looks like (and in some ways behaves like) a separate process.

简言之，每个线程看起来都像是一个单独的进程(其行为的某些方面也是如此)。
