From the GLX 1.4 specification:
Ancillary buffers are associated with a GLXDrawable, not with a
rendering context. If several rendering contexts are all
writing to the same window, they will share those buffers.
This is why so much of GLX is so painful -- even across address spaces,
drawables have to share buffers.
