So if I read this correctly then TZ10 should be polled every second
(check) and the temperature function contains a `sleep(1 second)' (which
explains the mysteries delay) followed by the Notify() (which schedules
the worker).

Now I'm curious if Windows has the same ACPI tables and if so how they
behave here. And what the actual plan here was. And where is the border
when one is actual allowed to make fun of someone. So many questions.
