i'm using a modified version of dns.  i found that aktomi
redirections too unreliable.  even so, i still get crashes, which have
become more frequent in recent weeks.  i've attached a copy of
"restartdns" which is ment to be called from cron on short intervals.

contrib quanstro/ndb has the whole nine yards.

one of these days i will redo dns with a better (and maintainable)
structure.  :-).  but please beat me to it.
