The last thing that I do not think is correct is this part. We are
setting the runtime here based on the number of CPUs and not based on
the number of actuall test iterations.

I guess that we need to:

  Turn the x86_pkg_temp_tz_found into a counter and collect the number
  of thermal zones found and set the runtime at the end of the setup
  with the counter instead.

And at the same time the TEST_RUNTIME appears to be significantly
smaller than the actual runtime.

  The upper bound for the runtime is a sum of all possible iterations,
  if we simplify it a bit it would be roughly ((RUNTIME+SLEEPTIME) *
  (SLEEPTIME/2))

  As we are doing SLEEPTIME iterations with SLEEPTIME and RUNTIME
  getting smaller in each of them so it will average out to SLEEPTIME/2
  iterations with full (RUNTIME+SLEEPTIME)

  So I guess that we need:

  #define TEST_RUNTIME ((RUNTIME+SLEEPTIME) * (SLEEPTIME/2))


The rest looks good to me.

With the runtime calculation fixed:
