recursion possibilities of bind is very pity in compare with 
powerdns-recursor, unbound & so on. It allocate a lot of memory and make 
high CPU usage.

Sometimes unable change authoritative and recursive IPs.
The decision is:
Authoritative q: bind answer it
Recursive: pass from bind ACL and proxy all recursive queries to special 
recursion daemon.

It'll be very useful option.
