Out of curiosity, the GTT mmap also failed? If you didn't have enough
virtual space for one mmap, the other should also fail.

How important is the requirement to flag GL_NO_MEMORY rather than
explode? Even for batch reset, we should still be able to propagate the
error back to the context (and cancel the operation to prevent further
dismay, or install some dummy).
