I don't run a nameserver, so forgive any obvious mistakes, but
adding something similar to a cron job might work:

# The following two lines should be on one line
*/10 * * * * host myhost.mydomain mydns.mydomain ||
  /etc/init.d/named restart

I don't know if you are supposed to be able to count on host to return
non zero if the lookup fails. On my debian box host acts that way, on
my Redhat box host appears to return zero whether it is found or not.

Redhat's man page (RH 7.2) doesn't specify behavior, Debian's does.

HTH,
