I think he just meant 57C.  In any case, we decided to set the _TMP poll
interval to 10 seconds.  After 2 readings above _CRT/_HOT, userland
receives an event and a message is logged saying the temperature is too
high.  On the 3rd one, we shutdown/power off the system.  I think Linux
chose something similar or at least I saw patches for that.

But 57C (or even 67C) is pretty low for _CRT.  We should probably add an
override.
