I don't see your point now. I'm afraid that you will have to live with 
the fact that you can not disable sending queries from BIND when it 
needs them, you can only prevent it by configuring BIND (so it will not 
need them) or firewall such packets so they will not get outside (which 
may break its functionality).

Maybe ISC will patch BIND to use system resolver for internal queries, 
but I doubt so. Maybe you can do it but imho it's not worth trying.

Maybe you can set up forward only; and forwarders {}; so BIND will 
forward all recursive queries it generates to your recursive servers.

But the way you are trying to get over this, I'm afrait you will fail 
and that's what I am trying to tell you.
