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.
