James Bursa identified a libcurl HTTP bug and a good way to repeat it. If a
site responds with bad HTTP response that doesn't contain any header at all,
only a response body, and the write callback returns 0 to abort the
transfer, it didn't have any real effect but the write callback would be
called once more anyway.
