As r600_exa.c doesn't set the EXA_SUPPORTS_OFFSCREEN_OVERLAPS flag, there
should be no overlapping copies from the defragmentation. I suspect the problem
is that exaOffscreenAlloc() may trigger defragmentation in the middle of
whatever. I'll probably just remove that and only keep the defragmentation at
regular intervals.
