Fetching a url with url-retrieve can reult in an anrbitrary buffer
being killed if a 401 (or possibly a 407) result is encountered:
url-http-parse-headers calls url-http-handle-authentication,
which can call url-retrieve.
This results in the current buffer being killed, and a new http buffer
being generated. However, when the old http buffer is killed, emacs
picks the top buffer from the list as the new current buffer, so by the
time we get to the end of url-http-parse-headers, _that_ buffer is marked
as dead even though it is not necessarily a url buffer, so next time the
