On the subject of process priorities, has anyone else noted that current
priorities frequently don't age properly (i.e.  not at all)?

For example, if you have a process at priority 3/14 and another at 2/6,
both performing cpu intensive tasks, the one at 2/6 appears to get no
cpu time, and the current priority is stuck at 2.  My understanding of
what should be happening is that the priority should age up to 6.  After
the high priority process finishes a time-slice, it's priority should be
3 and the second process should swap in.  However, this is not what
seems to happen.
