Another good thing is a crontab job which makes a rotating gzipped copy of
the db. I shuffle from mud.db.0.gz through to mud.db.9.gz. When pumping in
a new copy, the .9 file drops off and get's lost, which is a good thing if
you have a large db.
You will want to remember to use nice when doing the gzip to avoid lag.
