Because the pattern demonstrated above is so effective, it is relatively simple to extend it by chaining additional thread pools with queues.
因为上面介绍的模式非常有效，所以可以通过连接附加线程池和队列来进行扩展，这是相当简单的。

In this example, I don't focus on other issues related to this pattern, such as synchronization to make it thread safe.
在此实例中，我并没有针对其他与此模式相关的问题，如保持同步以确保线程安全。

Since it is thread safe by design, you might cache it in a public static final variable, or wrap it in a singleton pattern after creation for later access.
