Yes, there are problems with the active/expired arrays but they're no
worse with smpnice than they are without it.
With smpnice, if we make any wrong decision while moving the high and
low priority tasks, we will enter an endless loop(as load balance
will keep on showing the imbalance and move_tasks will always move
the wrong tasks, instead of the correct ones pointed by imbalance..)
This will only happen if the load weight for the task moved is larger
than the difference between the weighted loads for the two queues. So a
check based on this observation can be used to prevent the loop.
