Yes. It's used for all resource-related pfNotifies: Memory, Texture, Window,
clock, light-sources, pipes, etc.
You can always compare the error string (yuck), but why ? The Notify handler
doesn't provide a way to fix the out-of-memory condition. It only lets you
shutdown your processes gracefully. Am I missing something ?
