    kernel - Start work on a better burst page-fault mechanic
    
    * The vm.fault_quick sysctl is now a burst count.  It still
      defaults to 1 which is the same operation as before.
    
      Performance is roughly the same with it set to 1 to 8 as
      more work needs to be done to optimize pmap_enter().
