Ended the above FF, ksnapshot selection still lagging and jerky, CPU
dropped another few points to hover around 53% or so - some improvement.

Ah! I just noticed that user still has the check for updates showing on
the panel. I'll disable it, log out and in and see what X shows for CPU
usage then.

Ending Evolution dropped CPU usage on Xorg down another 3% to ~50%.

Anyway, logging the user out and back in, the panel shows no checking
for updates. Ksnapshot selection for the other user still lagging and
jerky. CPU usage now bouncing 49%-53% with only this message composing
going on and the other user on the other X session just sitting with
open terminals and some openoffice spreadsheets open. soffice.bin
showing about ~9%-~12% CPU usage.
