What is it called when your Mac doesn't fully crash? What is it called when an app crashes and it ends up logging you out, without restarting your computer?  The computer never fully turns off because the /tmp fold doesn't get reset.
This is most often caused by the WindowServer process crashing. However, there's not really a name for this specific type of crash.

On iOS it corresponds to the Springboard crashing, which is then named "springboarding".

However, no such name exists in common use for macOS.
