I use  two DNS servers both multi homed (per RFC). Haven't had any 
issues. I set my default TTL's for about 1 hour,
(10min for dynadns hosts).   And since both servers don't  recycle in 
the same minute..one of them will take
all the incoming requests while the other  restarts. -- all of 10 seconds.

I use a shell script wrapper (trigged from  inittab ) on mara,  with a  
-e flag.
If a certain file   /999-dns-down   exists, it just sleeps for 60 
seconds and exits instead of running mara.
That way I can still shutdown DNS without it respawning or racing.

If there are many requests for a dns update in the webadmin (over 30 
updates),
it can trigger a restart instead of waiting up to 14 minutes for the 
next batch.
