If you are going to query something that isn't your own named, it
sounds like a bit more work than I would do for a quick hack.
Come to think of it, I wonder is a simple "host" waiting to resolve
the hostname would be good enough as a self-adjusting wait for the
nameserver to come up. eg. before doing the ntpdate, run:
host -w -W 120 us.pool.ntp.org || echo "named is sucking mud again"
