Python请求模块连接超时

Python requests module connection timeout

我在查看http://docs.python-requests.org/en/latest/并将"连接超时"列为一个特性。但是，当我进一步阅读时，它指出

timeout is not a time limit on the entire response download; rather, an exception is raised if the server has not issued a response for timeout seconds (more precisely, if no bytes have been received on the underlying socket for timeout seconds).

这听起来不像是对连接超时的描述。我看到的是连接成功，它上载一个大文件，然后等待响应。但是，响应需要一段时间，然后超时。

如何设置连接超时，但在连接成功后仍等待慢速响应？谢谢。
