That statement is not true for 3.x.  The database library
is able to shrink a db file.  But in practice, you won't
see ovdb shrink unless something drastic happens like the
sudden loss of a bunch of articles (e.g., lose a CNFS buffer).

As long as expireover is being run regularly (from news.daily)
the size should reach an equilibrium and stop growing at some
point.
