this might be too aggressive since the BIOS currently only polls every 10
seconds and might have slight impact on power draw as well.  I would say sleep
for > 10 seconds here.  Maybe pass the amount of time to sleep as a parameter
run_once with a default setting of 10 seconds.

Done.

use c instead of w.  The first letter indicates the unit, deg centigrades
instead of watts.

Done.
