使用ctrl+c强制退出时，_process_polling_result无法处理异常

主动关闭主进程后， self.notify_queue，无法与主进程通信抛出异常。但是未做处理
怎么自己的代码中在生成对象后，遇到ctrl+c时处理这个错误呢

Start with nacos/client.py at _process_polling_result and reproduce the Ctrl+C shutdown described in the traceback on Windows. Trace how notify_queue is closed when the main process exits, then determine the expected behavior for the resulting EOFError; done means the shutdown path no longer produces an unhandled exception.
