<h2>9.1. 竞争条件</h2>

<p>在一个线性（就是说只有一个goroutine的）的程序中，程序的执行顺序只由程序的逻辑来决定。例如，我们有一段语句序列，第一个在第二个之前（废话），以此类推。在有两个或更多goroutine的程序中，每一个goroutine内的语句也是按照既定的顺序去执行的，但是一般情况下我们没法去知道分别位于两个goroutine的事件x和y的执行顺序，x是在y之前还是之后还是同时发生是没法判断的。当我们没有办法自信地确认一个事件是在另一个事件的前面或者后面发生的话，就说明x和y这两个事件是并发的。</p>

<h2>9.4. 内存同步</h2>
|
||||
<p>你可能比较纠结为什么Balance方法需要用到互斥条件，无论是基于channel还是基于互斥量。毕竟和存款不一样，它只由一个简单的操作组成，所以不会碰到其它goroutine在其执行“期间”执行其它逻辑的风险。这里使用mutex有两方面考虑。第一Balance不会在其它操作比如Withdraw“中间”执行。第二（更重要的）是“同步”不仅仅是一堆goroutine执行顺序的问题，同样也会涉及到内存的问题。</p>

<h2>9.5. sync.Once惰性初始化</h2>
|

<p>如果初始化成本比较大的话，那么将初始化延迟到需要的时候再去做就是一个比较好的选择。如果在程序启动的时候就去做这类初始化的话，会增加程序的启动时间，并且因为执行的时候可能也并不需要这些变量，所以实际上有一些浪费。让我们来看在本章早一些时候的icons变量：</p>

<h2>9.7. 示例: 并发的非阻塞缓存</h2>
|
||||
<p>本节中我们会做一个无阻塞的缓存，这种工具可以帮助我们来解决现实世界中并发程序出现但没有现成的库可以解决的问题。这个问题叫作缓存（memoizing）函数（译注：Memoization的定义： memoization 一词是Donald Michie 根据拉丁语memorandum杜撰的一个词。相应的动词、过去分词、ing形式有memoiz、memoized、memoizing），也就是说，我们需要缓存函数的返回结果，这样在对函数进行调用的时候，我们就只需要一次计算，之后只要返回计算的结果就可以了。我们的解决方案会是并发安全且会避免对整个缓存加锁而导致所有操作都去争一个锁的设计。</p>
