Yes, no issues with kde 4.2.0.  What happened is I'd upgraded to the bad 
nvidia-drivers-180.35, downgraded to 180.29, then upgraded kde from 
4.2.0 to 4.2.1.  One weird side-effect of the 4.2.1 upgrade is that I 
lost my plasma desktop layout.  No biggy, I just added the plasmoids 
back.  Then I noticed the lancelot cpu usage issue.  I have not noticed 
any behavior problems.  Kde 4.2 has been rock solid.

All I can think to try is to move my ~/.kde4.2 directory and let it 
regenerate.

Thank you,
