DNS caches that support partitioning ?

Are there DNS caches that allow you to partition the cache for
subtrees of DNS names?  That is, you can say that all entries from
say, in-addr.arpa, are limited to 20% of the cache.

The application I have in mind is to see if it helps to keep DNSBL
traffic, which caches poorly, from pushing other stuff out of the
cache, but there are doubtless others.
