Right, because in Vedran's latest oom log it shows that Xorg is preferred 
more than any other thread other than the memory hogging test program with 
your patch than without.  I pointed out a clear distinction in the killing 
order using both total_vm and rss in that log and in my opinion killing 
Xorg as opposed to krunner would be undesireable.
