Mark,
Roger that. Investigating that further on my part reveals that to be the 
case, as you said.

Yes, I was not setting "+norec" on my test queries, so this behavior is 
accurate. What is the exact significance of BIND 8.3.3-REL-NOESW; does 
BIND 9 behave differently in this case (noting that these ordb servers 
are open recursives, which I've contacted them about)?

Not a bug. :)

What is the different between 9.3.2-P1 and 9.4.0b2 that causes the 
difference in how this situation is logged?

Thanks for the great explaination!
