In general, I personally don't think it ever makes sense to shutdown
by default when the temperature is exceeded, since most of these

them over i2c, with potential bus locking issues and race conditions
with BIOS / IPMI; getting a bit sidelined, at the very least, the
sensor values should be dampened, which is what's done in OpenBSD's
sensorsd, not sure if anything similar is done here).

I disagree with this.
On my IBM ThinkPad z60m, the fan is so knackered it has to be on it's
side when compiling. If the BIOS thinks it's too hot then emit's some
warning bleeps. If it gets hotter then it powers itself down.
I would much rather the system shutdown gracefully compared to having
the power rudely yanked.

Wouldn't the correct solution then be to kill the process-intensive jobs, instead of shutting down the whole system?
