在这里，我想一方面可以复用对象， 另外一方面心跳的一来一回正好和它的两个指针(write 和read)很像. 另外数组的实现比链表对CPU更友好

@Terry-Mao 关于这个请教一个可能比较业余的问题。这里面的wp和rp都一定能保证原子性么？否则的话为什么就能保证线程安全呢。
另外有看到例如缓冲池的大小设置为5，如果消费能力很差的情况下，客户端连接就会断开，这个是出于什么目的呢？

能保证原子，取决于CPU 平台，64的话，确实是原子，但是 不一定goroutine 可见，这个是一个问题，可以用atomic来处理，目前相对比较少遇到这种问题（不可见），不过确实不安全
缓冲池，根据业务可以调整；
