Then just overheat and die. In-game dying of overheating is also a part of gameplay.
Avoiding dying through game-exit when you know you will die from overheating smells like a cheating.
How you think, why overheating is implemented to the game? To do menu-exit? Or try to not overheat and destroy the ship if you overheat?
In a case of CZ or any other combat situation, you always can do 15 high-wake

Instead of pushing iQuit buttons.
From you all repplies result only one thing. You do not want to exit a game because there is something urgent, but you want just to avoid desctruction when by the game mechanics your ships should be destroyed.
It not mean it is PvP, CZ, overheating. You just need to have a safe way of avoid rebuy screen. So cool
However, this way in most cases is High-Wake, and this is a better way, so insisting in 15 second exit, when you have 15 second high-wake is really strange
No my dear friend. 15 second charge, then you can whatever you want, even just turn off the computer (remember, the timing is so important! urgent matter arrived). In another system you have 0 delay. In any other situation than danger you have 0 delay. There is ZERO delay in supercruise.
So much of game loading and other fairy tales

Just 'move on'. Rebuy happens.
So much of urgent situations, just when You are in a 'danger'

What a coincideces.
