    [intel] Delay unmapping of driver-private buffers to reduce map/unmap thrashing.
    
    Good for a 10-15% improvement to OA.

    [965] Force a new vertex upload buffer at new batch time.
    
    Otherwise, we could choose to upload into the temporary VBO that we just fired
    off to the hardware.  Good for a 60% OA performance improvement.
