Coincidentally I looked into this today because we had totally
imbalanced queues when this was activated - slip through in the queue
assignment, should be fixed in our branches. v4 basically has all your
comment addressed, our branch(es) have 3 bug fixes now to what I thought
would be v4 - unless I get pulled into other things again (which is
unfortunately likely), v4 will come tomorrow.
