generally I agree with that.... :)

simply to say that, the more important a job is, it should be given
longer time to run... but, the process has privilege to yield before
time slice is up...and when it comes back,it will use the remaining
time slice.....and its dynamic priority will stay the same (that's the
property that I recall....)

well, you can think, what happen if you take the other direction for
the policy? higher priority, but less time slice? that, IMHO, is less
intuitive.
