Description of problem:
gnome-system-monitor causes 100% cpu usage when viewing "Resources". "top" shows gnome-shell using about 85% of cpu, and gnome-system-monitor using about 1.5% cpu. This is running X11.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start X11 gnome (classic) session
2. Start gnome-system-monitor
3. Switch to Resources tab
cpu usage climbs to 100% and stays there.
gnome-shell uses a reasonable cpu percent when gnome-system-monitor is viewing Resources.
There isn't any noticeable degredation of desktop response while this is happening.
