In many cases, we do not care about the total number of
messages. It's a rather expensive operation in SQLite
(Xapian only provides an estimate).
For LKML, this brings top-level /$INBOX/ loading time from
~375ms to around 60ms on my system. Days ago, this operation
was taking 800-900ms(!) for me before introducing the SQLite
overview DB.
