The above message contained the following:

Hold off.  We activated some loadable modules in the kernel that allows
you to monitor CPU temperatures (and other things).  You can run this
anytime you want, e.g.,

The temperature of your 2nd CPU (46.5 C) is getting up there, but 
they're currently both with operational parameters.

If and when you take the machine down, then you should check your BIOS 
settings to see at what temperature the machine with shut-off.

We're going to set-up a crontab(1) entry for user "ldm" to run this
every 5 minutes and concatenate the relevant output to the log file
~/logs/sensors.log (along with a timestamp).
