- Unbreak priority prop. for timeshare threads. Always place something on

the current queue if its priority is really elevated.  This needs more work
   as there are cases where a next queue kse could be holding up what would
   be a curr queue kse, and thus hurting interactivity.  Also, when a thread
   with an elevated priority has its priority lowered it should be placed
   back on the next queue.
