Streaming URLs hang HTTPoison

Hi,

I'm using HTTPoison to fetch html data from arbitrary URLs. But if a URL points to a stream, HTTPoison never completes the standard `HTTPoison.get`, and there's no completion timeout I can use (that I know of), since `timeout` is just for the initial connection and `recv_timeout` is for the beginning of the response (not the completion of the response).

Is there a way I can detect if a URL points to a stream with no size, rather than a response with a fixed size, so I can skip them? Or failing that, is there an option I can pass that will timeout of the request isn't completed in x seconds?

Thanks!
