--- Comment #14 from Chris Wilson <chris at chris-wilson.co.uk> ---
Found something that I didn't like, that would have caused a stutter for a few
frames.

sna/dri2: Free the pending back buffer after use
The pending back buffer is only the pending copy, the actual info->back
stores the client's view of the current back buffer which may be more
recent than the pending copy. So store the current back buffer, swap in
the pending to do the normal swap, then free the resultant back (which
may have been exchanged with the front), before restoring the client's
current back buffer.
