Why not just return NXDOMAIN if you are going to all of that trouble and be guaranteed that it'll work for standards-compliant caching resolvers? I don't see what would be available to gain by adding this extra complexity, and there's certainly a (much) lesser guarantee, or so I would tend to believe, that things will stop asking if they get an ICMP unreach as opposed to an NXDOMAIN.

or how about using an NS that returns ICMP errors instead of NXDOMAIN,
perhaps using anycast for reducing network load?
Would that stop the timeout errors? server is still lame, you just know
