does type forward zones make BIND 8 continuously poll?

[Anthony Golia]

I mean if I do this:

zone "foo.com" {
        type forward;
        forward only;
        forwarders {
                10.10.10.10;
                192.168.1.1;
        };
};

and things happen in this order:

-	192.168.1.1 is down
-	BIND comes up, requests for foo.com come in, BIND frwrds them to
10.10.10.10
-	10.10.10.10 goes down, 192.168.1.1 comes up, requests come in

how often does BIND send SOA queies for it's RTT calcs?  any help is
appreciated.
