Process.exit(self, :normal) inside process	Dies, does not kill linked processes	Does not die, receives message {:EXIT, from, :normal}
Process.exit(self, :some_reason) inside process	Dies and kills linked processes	Does not die, receives message {:EXIT, from, :some_reason}
Process.exit(pid, :kill) from outside	Dies and kills linked processes	Dies and kills linked processes
Process.exit(pid, :normal) from outside	Does not die, no message received	Does not die, receives message {:EXIT, from, :normal}
