Right. So in order to stay in the new_flows list, the flow needs to be
slow enough that no new data is added to it in the time it takes
subsequent dequeue invocations to get back to it in the old_flows list?

Yes, I think I missed this, and was somehow assuming that the flow stays
"alive" (i.e. in the old_flows list) for as long as the /connection/ is
up... :)
