This needs to be extended: checking the returned pointer is a preparation for when buffers can be deleted. As it is right now, checking for a NULL pointer isn't needed. I wonder if it isn't better to drop those checks and instead apply them at the tail end of this series when the actual work on deleting buffers starts (before patch 49, I think).
