From #7938
Avoid hanging on takeHeaders (incorrect 103 handling) when response body is empty.
If we mess up our logic (103 and so on), we call closeInternal on the stream from the timeout, but only if if source.isFinished() is false. For an empty body, this will be true, so the next waitForIo, would wait indefinitely.
