Round robin not cyclic

[Mark.Andrews at nominum.com]

	Yes, they are different.  In practice however it make little
	difference except with the very low query rates with long
	run times.  Note round-robin are statistically identical
	to each other.

	If you look at failure modes you most probably don't want
	either of round-robin or cylic.  'random' is usually better.
