嗯嗯，我也发现这个问题了，所以我在util.go里面写了一个ConnectionMap来管理客户端连接，它其实就是map加读写锁，所以效率较低。ConcurrentMap因为有死锁的bug，暂时没有使用，Github上有个项目go-concurrentMap，是高仿Java的ConcurrentHashMap，从测试数据来看效率非常高，如果你感兴趣可以看下，但实现很复杂，几乎是将Java的实现搬到Go来了，因为两种语言的内存模型不太一样，我没敢搬过来直接用，ConcurrentMap我还没来得及改，sorry

我能想到的一个折中的方法，就是先IterKeys()把所有的key遍历一遍，放到slice中，然后遍历slice，再逐个删除
