I tried that, pointing each DC to the other and my DNS resolving slowed 
to a crawl, hung for short periods and generally became unresponsive. I 
just have:

search <dns domain>
nameserver 127.0.0.1

on each DC, and everything works ok for me, my feelings are that because 
each DC runs a DNS server and replicates info to the others then each DC 
should be able to respond. If something has gone wrong with the DNS 
server then probably there are others things that have gone wrong and 
may not respond to any DNS request.

Pointing member servers & clients at both DCs is probably a good idea.
