  Log:
  MFC 1.32 and 1.33:
  - Set the priority of the page zeroing thread using sched_prio() when the
    thread is created rather than adjusting the priority in the main
    function.  (kthread_create() should probably take the initial priority
    as an argument.)
  - Only yield the CPU in the !PREEMPTION case if there are any other
    runnable threads.  Yielding when there isn't anything else better to do
    just wastes time in pointless context switches (albeit while the system
    is idle.)
