Compiz's sync to vblank option was already off.  Turning it on hung compiz, and
I had to switch to a VT and kill -9 it.

That reminds me, with the gallium drivers I have to have vblank_mode set to
something in .drirc, otherwise everything using OpenGL hangs.  With the classic
drivers I didn't even need a .drirc.  vblank_mode is currently set to 1.

Turning off EnablePageFlip and/or SwapbuffersWait doesn't help.
