I intend to do nothing.  It's up to the interface to handle this, if it
needs handling at all.

The interface could keep track of threads deleted/untagged and adjust
accordingly.

Or I suppose one could also implement --initial-msgid, --last-msgid,
--num-threads, etc.  Set --initial-msgid to the last message in your
current view.  Set --num-threads to 100.  That should do it.

Personally, I think users should be discouraged from scrolling and
scrolling.  Notmuch is a *search* tool.  If the mail you want isn't in
the first page or so, you're using the tool wrong.
