X server consuming lots of CPU cycles

[Paul Michael Reilly]

In the past few days I've noticed that the X server process is
consuming 20-80% of the CPU on a regular basis as opposed to a more
reasonable once in a blue moon.  I haven't updated in about a week and
was reluctant to do so until I saw a fix for the libXfont/xfs issues.
I don't suppose anyone else is seeing unusually high X server usage
recently or is aware of some change that would explain what I'm
seeing.  FWIW, I am running a A31p Thinkpad with 1G RAM and a 2+Ghz
processor.  The logs do not seem to show anything out of the ordinary.
