 SST_SWAP_EN_WAIT_ON_VIDSYNC=1

 If I understand the code correctly, one just has to wait for the vsync
 before dispatching the buffer swap.  Would this interfere with the
 normal operation of the X server?  What happens if there are several
 OpenGL applications running?  On an Octane (MXI) I can start four or
 five gears before the framerate starts to drop from 72 fps.
