With backboost, you take everything that overflows MAX_SLEEP_AVG and give
it all to the waker... you always pull-up. With back-theft (blech;),
there's constant pull-up and push-down for all parties instead of only
those who reach MAX_SLEEP_AVG, so while you'll still tend to group tasks
which are related (the original goal of backboost), it shouldn't (wild
theory) go raging out of control.
