Are you talking about me perchance? I don't really care about precision
_that_ much, though I certainly do want to tighten timeslice accounting.
No, sched_clock is fine to be used in CPU scheduling choices, which are
heuristic anyway (although strictly speaking, even using it for timeslicing
within a single CPU could cause slight unfairness).
I'm talking about the update_cpu_clock() / task_struct->sched_time stuff.
