DB4.0 has a known (cosmetic) bug that causes this number to monotonicly
increase (they apparently are missing a decrement).  So as long as it is
only increasing at a slow rate and you aren't seeing any other problems,
all is well with the world.

I don't believe any recent version of cyrus has a major Berkeley DB
locking problem.  Of course, we also recommend using the skiplist backend
for the mailboxes.db file.
