load average: 0.00, 0.00, 0.00

As I've mentioned great many times I run this test on a completely idle system
(i.e. I even `init 3` in advance to avoid any unexpected CPU usage spikes
caused by unrelated processed).

I have to insist that people conduct this test on their own without trusting my
words. Probably there's something I overlook or don't fully understand but from
what I see, there's a serious issue here (at least Microsoft XP and 7 work exactly
the way I believe an OS should handle such a load).
