Since then I have learned that this is an X library memory leak which the nv driver apparently triggers somehow. I've got an Xlib memleak patch I've just applied however i dont know if it has to do with this problem or not. I only know what people are bug reporting, and that disabling AA fonts in KDE solves the problem as a workaround. >In 4.1.0 and previous there was a serious pixmap leak in XAA >that happened when purging the cache, which the "nvidia" driver >did frequently when making room for textures when running 3D >apps.

If you're interested in seeing the bug reports we've got, let me know and I'll pass them along to you. I dont have hardware to be able to debug this myself however.
