Anything that uses shadow maps (or any other render-to-texture type effect) without framebuffer objects will hit this path. Since iD only uses stencil volume shadows, it's not surprising that you haven't hit it yet. And I don't think glTexSubImage is the problem, I think glCopyTexSubImage is the problem. There are also some Nvidia demos that use pixel buffer objects to do async. glReadPixels. I suspect that path will have the same potential problems.
