   1 The following demonstrates the cpudists program. It prints distributions
   2 of CPU time consumed by the Kernel, Idle thread, or Processes.

  42 The value indicates the time in nanoseconds, the count the number of
  43 runs for this length.
  44
  45 From the above, we can see the kernel has run many times - but for short
  46 intervals each time. Processes have taken fom 10 to 60 microseconds;
  47 and when the idle thread runs it runs for some time - around 8 milliseconds
  48 for each.
