Loop detection

Is it possible to configure bind8 (8.2.2-P5) so that it is able to
detect a loop if it "sends" a query on to a server configured in a zone
{type forward;}; clause if that "target" server is configured to send
back to the original server as a forwarder and reckons that it doesn't
know the answer?
Eg:
------------------------------------------------------------------
Main server (172.18.1.1) has:
zone "82.168.192.in-addr.arpa" {
type forward;
forwarders { 192.168.82.55 ; };
};
------------------------------------------------------------------
Sub-server (192.168.82.55) has:
No info on 82.168.192.in-addr.arpa (eg: accidental file deletion
other cock-up)
forwarders {
172.18.1.1;
};
------------------------------------------------------------------
I seem to recall I have seen messages about loop detection in the
syslog file but that may just work for sub-zones(??). If there is no
loop possible then the situation above leads to a rather fast "tennis
match".
