Under Windows there is no way to reliable determine the time a thread owned
CPU. Using existing APIs you can count quants, not the time. The problem is
that when the thread releases processor before it consumed the whole quant,
e.g. by entering non-busy waiting, the pending quant is not counted.
Theoretically you could have 99% CPU usage with 0% indicated in the task
manager.
