  SVN rev 215774 on 2010-11-23 21:36:53Z by uqs
  
  MFC r214237,214489:
  
  Remove mention of non-existant -o flag for debugging options.
  
  Fix CPU load reporting independent of scheduler used.
  - Sample CPU usage data from kern.cp_times, this makes for a far more
    accurate and scheduler independent algorithm.
  - Rip out the process list scraping that is no longer required.
  - Don't update CPU usage sampling on every request, but every 15s
    instead. This makes it impossible for an attacker to hide the CPU load
    by triggering 4 samplings in short succession when the system is idle.
  - After reaching the steady-state, the system will always report the
    average CPU load of the last 60 sampled seconds.
  - Untangling of call graph.
