I just tried this suggestion, and I'm not sure that it's a good thing
to do, it was taking a 'long' time (1 in 3-5 sec).  I have ~1700
articles (expiry of 60 days) and I don't have that long to wait.  It
also seems to loose any marks that have been applied to the articles
(expiry for example), and if you use expiry it will screw that up also
because it will change the modification time on the file, which nnml
uses for expiration.
