Round-robin refers to the order of the answers in a response.  To see 
this, do "dig yahoo.com a" several times and you'll see that the A 
records are in a different order each time.

It sounds like you're talking about the order in which it selects 
nameservers to send recursive queries to.  That is *not* round-robin.  
It remembers the response time of previous queries, and prefers servers 
that respond quicker.
