    sys/vm               uma_core.c uma_int.h 
  Log:
   - Remove the working-set algorithm.  Instead, use the per cpu buckets as the
     working set cache.  This has several advantages.  Firstly, we never touch
     the per cpu queues now in the timeout handler.  This removes one more
     reason for having per cpu locks.  Secondly, it reduces the size of the zone
     by 8 bytes, bringing it under 200 bytes for a single proc x86 box.  This
     tidies up other logic as well.
   - The 'destroy' flag no longer needs to be passed to zone_drain() since it
     always frees everything in the zone's slabs.
   - cache_drain() is now only called from zone_dtor() and so it destroys by
     default.  It also does not need the destroy parameter now.
