`gnus-fetch-headers' calls `gnus-retrieve-headers', which looks
to look in the cache first if `gnus-use-cache' is non-nil and
Gnus knows articles to be fetched.  Of course Gnus knows them
that are ticked and cached in such a case.  Actually I have such
articles (ticked and cached but expired in the server) but have
no problem.  It is because `gnus-use-cache' is `passive' in my
case, maybe.
