I guess even that makes sense...

But, out of curiosity, do you know which kind of device is that and in what
kind of environment? I mean, theoretically it may make sense on a cellphone,
but... I guess you have some fun device and would like to know what it is :-).

Hmm. And we can make this quite generic.

while (too_cold())
barrier();

Wasting power is really easy :-).
