nautilus uses ~10% CPU always

[Chuck Anderson <cra WPI EDU>]

Has anyone else noticed that nautilus just sits there using 10% of 
your CPU for what seems like "no reason"?  What might be causing this 
usage?

Occasionally, it has gotten stuck using above 90% CPU.  When this 
happens, my laptop CPU stays at 2.2 GHz instead of going to a slower 
clock speed and the fan stays on.  This can't be good for power 
saving.  I killed nautilus when it did this, and it respawned and then 
stayed around 10%.  Still seems like too much.
