Yeah, understood. This shortening of timeslice I think is generally
bad, (hmm...) though in an environment where preemption is rampant, this
shortening of slice should lead to a throughput gain for low ranking
_interdependent_ tasks. Is that what you're trying to accomplish? To
reduce latency at the bottom in the face of preemption from above?
