In your estimation, a named/BIND bug, or OS level bug? How would one
go about finding out, and working it out, so we can solve this? I can
certainly and very easily shove a launchd job in to run every 5
minutes, and do not even consider it much of a kludge, but would like
to solve it for others, as it is a bear to track down.
Myself, knowing about it, and having hit my head against it, failed to
remember it again.
