drop a lot of older stable stuff ...

Xorg is competing heavily with FF for top hog on my system. In FF I
understand because I had multiple windows (6 desktops) with many tabs. I
know this would theoretically increase Xorg work as well but prior to
this update I seldom saw it near the top of "top"

Anyone else pound the crap out of a desktop with FF and see Xorg getting
"fat"?

TIA for any clues or response.
