Jefferson wrote "if the main thread has died", and lopsided98 wrote "exiting the main thread".

So it's not yet clear if you are both saying exactly the same thing. It depends on Jefferson's intended meaning of "died": If the main thread is blocked or busy-waiting for an event that never occurs, it could be considered to have "died" but not "exited".
