  Log:
  Avoid the unnecessary acquisition of the free page queues lock when a page
  is actually being added to the hold queue, not the free queue.  At the same
  time, avoid unnecessary tests to wake up threads waiting for free memory
  and the idle thread that zeroes free pages.  (These tests will be performed
  later when the page finally moves from the hold queue to the free queue.)
