I was trying to add two sets of data to my last post. Here is the other one. Please note the titles in the plots.

What I would like to learn to do if a developer could point me in that direction is attach to the compiz process, and actually try to see what is process in compiz is eating the CPU. I cat attach with gdb, but I want to output the currently running function. My thinking is that after some time, one is more likely to be caught inside the process which is eating the CPU. With enough data points, we should statistically be able to track down which process (or maybe several processes) is unstable.

Speculating here... could this be a loop that slowly increases with time ? This linear degradation is a nasty bug !

By the way, two questions with launchpad:
1. How can I attach multiple files to a comment ?
2. Can I edit the description of an attachment on a previous comment ?
