F10 - gnome-screensaver misbehaving?

[Michael Cronenworth]

I've been noticing Xorg has been taking a nice chunk of RAM after 
upgrading to Fedora 10. I decided to start up xrestop and see what's up:

xrestop - Display: localhost:0
           Monitoring 35 clients. XErrors: 0
           Pixmaps:   95419K total, Other:     219K total, All:   95639K

That's the top two items in my list. Is there any particular reason 
gnome-screensaver needs 40 megs of RAM? Yes, I'm running XFCE4 on this 
system, but I have seen the same behavior on a Gnome desktop running 
Fedora 10.
