There are some broken resolvers *cough*OS X*cough* which will not correctly round-robin through the list of DNS servers, or will cache the IP of the first server that responds and continue to try that address. Using CARP on your DNS servers (possibly in an active-active configuration) will help to deal with broken resolvers if one of your DNS servers goes down. It's up to you to decide if the added complexity is worth it.
