It doesn't seem to me as sane to consume this amount of CPU time to poll for
anything (see attached screenshot). I figured a way how to reproduce this, I've
enabled RandR polling in KDE, attached LCD TV via HDMI and played a video in
VLC. After few mouse clicks in the menu of VLC I've witnessed jerky mouse
movement and later my X has frozen completely. I've switched to console and
found out that when I unpluged HDMI the kworker process went quiet.
I was able to take one screenshot but as my X froze I saw 3 kworker processes
running, eating all CPU time rendering my system useless (no chance to take
screenshot at that moment).
I repeat I'm running latest gentoo-sources-2.6.37.
