Even if BIND had negative caching, it wouldn't help much in this case.
The problem is that there wouldn't be any queries for just "UUCP". Your
local name server would forward queries for foo.UUCP and bar.UUCP to
the root servers, which would return a no such domain response. Your
local server would cache this information for foo.UUCP and bar.UUCP,
but when it received a query for baz.UUCP, it would still forward it
to the root servers.
