+// 这个字典在HTTPDNS中只用于存储HttpdnsHostObject对象，这个对象是整个框架的核心对象，用于缓存和处理域名解析结<E69E90><E7BB93>?
+// 通常从缓存中获得这个对象之后，会根据不同场景改变一些字段的值，而且很可能发生在不同线程<E7BABF><E7A88B>?
+// 而不同线程从缓存中直接读取共享对象的话，很有可能发生线程竞争的情况，多线程访问某个对象的同一个字段，在swift环境有较高概率发生crash
+// 因此，除了确保字典操作的线程安全，拿出对象的时候，也直接copy一个复制对象返<E8B1A1><E8BF94>?HttpdnsHostObject对象实现了NSCopying协议)
