I was afraid you'd say that.  :-)

I've now experimented a bit with the function `A T' command, and I
found that for me, the main problem was this code:

    ;; We want to fetch LIMIT *old* headers, but we also have to
    ;; re-fetch all the headers in the current buffer, because many of
    ;; them may be undisplayed.  So we adjust LIMIT.
    (when (numberp limit)
      (incf limit (- gnus-newsgroup-end gnus-newsgroup-begin))))

In some groups I have dormant old articles, and this means that this
will fetch an enormous number of messages.  I've just removed this,
and had it fetch the previous/next 200 messages in the group.  This
seems to do the trick most of the time, actually.
