Yeah, they're back to back repeats. Using dirt simple massive_intr didn't help clarify aim7 oddity.
aim7 is fully repeatable, seems to be saying that consolidation of small independent jobs is a win, that spreading before fully saturated has its price, just as consolidation of large coordinated burst has its price.
Seems to cut both ways.. but why not, everything else does.
