oops sorry I misread your mail (lack of early coffee I suppose)

I can see your point of having a thing for "did we ask for all the performance
we could ask for" prior to doing a load balance (although, for power efficiency,
if you have two tasks that could run in parallel, it's usually better to
run them in parallel... so likely we should balance anyway)
