I got the leaks no matter which nvidia binary I use.. but then who knows, it 
could have been fixed while plasma was leaking... Meh.

Anyhow after doing some testing, it does look like it only happens with 
nvidia's binary driver with glx and compositing enabled. Maybe nvidia will get 
on it asap, we'll see, I've got a thread going on the nvnews linux forums as 
well. Going to leave my system running nvidia without glx for a time to see if 
indeed plasma will leak over the long term but I'm skeptical. Especially since 
I'm not testing the same variables anymore, before it was always plasma with 
compositing of some form, now without glx, no compositing of any form is 
available afaik, so its not exactly a proper test.

small note, compositing/argb visuals make plasma's pixmap mem use skyrocket. 
18MB with no compositing on nvidia, with composting on either driver pixmap 
use starts at 32MB, and tops out at 130MB after a couple hours with 
nv+xrender.
