Well, there's just two processes that I couldn't find information on  
online though, kintegrityd and kworker. I set them to highpri for the  
moment, in my script. However the script didn't seem to make much of a  
difference, so the processes that run on Ubuntu Natty Narwhal seems to be  
quite well behaved. It's just a principle though, that any background  
processes shouldn't be able to request a lot of cpu, while I am running my  
opengl app. I do see that the ubuntu folks have reniced some processes of  
their own though.
[khelper] [kintegrityd] [kblockd] [kacpid] [kacpi_notify] [kacpi_hotplug]  
[ata_sff] and more are all at -20. Seems to be quite the opposite of what  
I am doing...
