    powerd - Do a more sophisticated domain scan, use kern.usched_global_cpumask
    
    * Do a more sophisticated domain scan, cpu domains do not necessarily start
      at 0.
    
    * Handle the case where multiple cpus may belong to a single domain.
    
    * Dynamically adjust kern.usched_global_cpumask to the number of cpus we
      are running at max frequency, leaving the remaining cpus set at their
      lowest frequency and left mostly idle.
    
    * Tested on the 48-core monster and phenom x 6.
