                         vm_pageout.c vm_pageout.h 
  Log:
  Implement a VM load heuristic.  sysctl vm.vm_load will return an indication
  of the load on the VM system in the range 0-1000.
  
  Implement a page allocation rate limit in vm_fault which is based on
  vm_load, and enabled via vm.vm_load_enable (default on).  As the system
  becomes more and more memory bound, those processes whos page faults
  require a page allocation will start to allocate pages in smaller bursts
  and with greater and greater enforced delays, up to 1/10 of a second.
  
  Implement vm.vm_load_debug (for kernels with INVARIANTS), which outputs
  the burst calculations to the console when enabled.
  
  Increase the minimum guarenteed run time without swapping from 2 to 15
  seconds.
