You would think, but I've noticed that on HN specifically, the comment pointing out that a stupid argument is forming--if it gets in early enough--tends to be both highly upvoted, and the end of the argument. One reason I like this community.
There was no argument, whether "stupid" or not. You're welcome to start one.
There already was another comment pointing out that one could kill the process from another tty.
I interpreted "Crashed my whole system" as meaning that option wasn't possible.
