The lack of concurrent lookups was a minor one of my complaints.
Being set up to cache negative responses by default is another and
caching A records at a level that doesn't understand round robin DNS
is another - it stopped one of my mailservers being able to fallback
to a backup mailserver on many occasions until I forcibly ripped it
out being one of the more major complaints.
If you need it for passwd or other caching, fine (you can set it to
just cache the things you want it to cache), but using it to cache DNS
is broken. This is what caching name servers are for.
