Unless someone has a really nice DNS monitoring add-on that they can
share, my suggestion for carefully monitoring DNS latency would be to
use Smokeping:

It does a better job at DNS latency as it will send many queries over a
shorter period of time and graph them in a really useful way.

Smokeping is totally awsome, and I've seen it do DNS monitoring well before
(and something I'm planning on implementing soon).  The BIG benefit of
smokeping is that it displays its graphs so you can see even little
problems at a glance.

Of course any "probe" technology will only provide a small sample of the
queries.  The BIND stats file provides a break-down of latency in ranges of
which can be turned into a graph.
