GShader thing?

ESC                 = exit demo
left mouse + drag   = rotate camera

0.044960 FPS (1 frames in 22.242000 seconds)
0.047201 FPS (1 frames in 21.186000 seconds)

ESC / CNTRL+C (several/hundred times)

=> 2 times switching between blank (black) full screen (console) and desktop
(KDE 4.13.3) before the system comes back

NO, no LLVM this time... (Michel?)
