 > Yes, I have only observed the hog when using an XO activity, always
 Browse-95, plus sometimes also Terminal, Journal, Pippy, Measure, Logs,
 Firefox-4.xo.  I avoid running more than 3 activities.

 Shooting in the dark but... can you try to launch Firefox (perhaps a few
 times) and see if it causes the cpu hog?

 > So I suppose sugar-shell is the sugar GUI.  Maybe the hog correlates
 with particular sugar features such as clipboard items or keyboard cheat
 codes or keyboarding errors, or persistent pallettes.  Spinning code?  To
 be tested...

 My main suspect is the spinning icon that you get when you start an
 activity. I'm going to attach a patch to disable that animation. If you
 could apply it and see if it fixes the problem it would be very useful. As
 root:

 cd /usr/share/sugar/shell/view/
 patch -p0 <path_to_the_patch
