xfree86 Process Using Over 50% !?

[Robert Tilley <tilleyrw@cfl.rr.com>]

I have been running KDE 2.2.2 (my unstable system is apt-get updated daily) 
and noticed that the xfree86 process (according to top) was consuming over 
50% of CPU resources at times.  Sometimes only 11%, sometimes 30%, sometimes 
over 50%.  Strange and getting stranger as this only began occuring in the 
past few weeks.

So I tried out Blackbox with gkrellm and immediately noticed that my total 
CPU usage (with the same processes as under KDE -- browser, mail, news, etc.) 
never went over 12%.  Something in KDE was consuming mucho CPU.

Any ideas on why this might occur?
