   代码头有段注释， 虽然有点难理解，还是能够帮助理解这么写的意图：
   
   ```
   /**
    * CLIENT_POOL是一个完备的连接池，支持向同一个目标建立一个或多个连接
    * 之所以再包装一层，是因为多个线程使用一个连接池的场景下
    * 会导致多个线程抢连接池的同一把锁
    * 包装之后，允许使用m个网络线程，每个线程中有1个连接池
    *
    * support both sync and reactive invoke.
    * 1.sync invoke, bind to a net thread
    * 2.async but not in eventloop, select but not bind to a net thread
    * 3.async and in eventloop, use clientPool in self thread
    *
    * sync/async is not about net operation, just about consumer invoke mode.
    */
   ```
