Under 11.10, I don't have permission to renice processes using the Gnome System Monitor

[Steve Brack]

No matter which way I attempt it, whether from the app's main menu or from the context-sensitive (right-click) menu for a process, I get a permission denied error when I attempt to change the "nice" level of a running process. The only way I can do it is if I open a terminal window and execute the "renice" command using "sudo" to run it as root. I never had to do that before I upgraded to 11.10, as far as I can recall.

This appears to be an issue with requiring root-level privileges to make the change, as executing "renmice" without "sudo" also results in a permission denied error.
