High load ave after f10->f11

[Neal Becker]

After update f10->f11, load ave is high due to:
2174 root      20   0  605m 183m  10m R 29.3  9.2  25:59.11 X
 2786 nbecker   20   0  453m  37m  23m R 22.9  1.9  16:58.91 kwin

This is on nvidia proprietary driver.  This did not happen under F10.

Tried turning off compositing using C-S-F12.  Did not help.

Now performing massive update, perhaps that will help.

Anyone else see this?
