  Log:
  If the temperature is at _HOT or _CRT for 3 sequential readings, shutdown
  the system.  Also, decrease the poll interval to 10 seconds from 30
  seconds.  This is needed because some systems will report an invalid high
  temperature for one poll cycle.  It is suspected this is due to the
  embedded controller timing out.  A typical value is 138C for one cycle on a
  system that is otherwise 65C.  This prevents the system from prematurely
  shutting down after one invalid reading.  It will still shut down after 30
  seconds of high temperature, which is the same as previous default
  behavior.
