Honestly, running out of memory isn't the best example for vertical integration of the OS. While it can behave reasonably on Windows, OOM is still the one thing that that can still sometimes bring down every OS to an unusable state, including Windows. But barring that, best of luck trying to bring down the GUI on Windows. Whereas with Linux, you always gotta be ready to drop out of your GUI and into a terminal to rescue stuff.
