sendmail: persistant read lock on aliases.db

Is anyone else seeing sendmail processes that maintain a persistant read
lock on their aliases.db file? It would look like this in lsof:

sendmail 9229 root 7rR VREG 2137,826253 10592256 443 /var/adm/sendmail/aliases.db

Since this sendmail process has the aliases.db file locked, that file can't
be rebuilt with newaliases.

I've seen this happen on a variety of 4.0f and 4.0d systems over the years
but I'm just now getting around to trying to figure out why it happens.

The workaround: Killing the sendmail process which holds the lock.
