Still the same power counting bugs than previous versions.
After a few minutes, on battery, it went from 12W to 20W because of an
rsync in the background, and when that rsync was finished (sigstop), I got this.
Somehow I very much doubt that e17 was using 1550W.
Clearly there is at least an assert missing that should ensure that the list
of power estimated values clearly exceeds the total power.
Even if I stop enligthenment, which seems to be most of the wakeups, bad
accounting is all wrong in many ways, see below:

No, alsa isn't using more battery than the total laptop either ^^^
Ok, let's wait a bit longer:

Ok, so I killed pulseaudio, which I'm pretty sure is not to blame, and now I se
this. So you get the idea, 621 wakeups per second isn't good, but the accounting
seems to be wrong.
