这个控制它的过程很耐人寻味，很有意思，但是计算机的核心仅仅只是，我们在初始指令序列上，建造描述、方法的一个概念罢了。

The process to control it is intriguing and interesting but the heart of the computer is simply this notion that we build our descriptions, our recipes, on a sequence of primitive instructions.

对每一个非初始化堆指针存储，卡片标记算法可以只增加两到三个机器指令，并要求在小的收集时对所有脏卡片上的对象进行扫描。

Card marking algorithms can add as little as two or three machine instructions per non-initializing heap pointer store, and entails scanning any objects on dirty CARDS at minor collection time.

这些指令大多数是为了检查i的初始化，以及使用锁执行线程安全的初始化。

Most of these instructions are in place to check for the initialization of I, and to perform a thread-safe initialization using a lock.
