  • We need to re-sort ready_list after updating all the priorities. Expensive, but no way around it I think.
  • PRI_UPDATE_FREQ is a separate value from TIME_SLICE, they just
    happen to be set the same.

LGTM!
We had a function to resort the ready list that was then removed as it turned out it was not necessary in our case.
It is also a good bet to resort even if it was unnecessary as O(n log n) will be better than repeated O(n) for large enough number of n.
