这个古老的话题,
首先让我们看stackoverflow中一个经典的问题:
然后连接看答案:
https://stackoverflow.com/questions/154551/volatile-vs-interlocked-vs-lock
这里的误区,主要是对volatile的解释和使用;
关于volatile的解释和示例:

这里还有一篇较好的文章:

一些文字摘要:
The memory model is a fascinating topic – it touches on hardware, concurrency, compiler optimizations, and even math.
The memory model defines what state a thread may see when it reads a memory location modified by other threads. For example, if one thread updates a regular non-volatile field, it is possible that another thread reading the field will never observe the new value. This program never terminates (in a release build):
这里我们再进行 synchronization 中 Barrier 的使用;

它的另外一种用法滴啊;
