I just updated to from Intrepid to Jaunty, and I noticed something curious.
I believe this is a bug, but even if it isn't, I thought it should be
If a cpu (or core) is set to "Ondemand" and an application with a high nice
value is running:
- In intrepid, the cpu remained scaled down
- In jaunty the cpu scales up to 100%
I found a website  which does a good job of explaining it, and I tried
setting my ignore_nice_load to 1, but nice processes still scale the
processor up. Unless I am mistaken, this is a bug. What information should I
attach to the bug report?
