[CentOS] Request for bind large systems build

It would be nice (if not already available) to get a bind build with -with-tuning=large in the configure, this sets bind/named to run 'better' on large memory (read production) systems.

If someone could point me at an official one, or consider this as a request for a bind.large.systems.x86_64 package to be in the main repos that would be great.
