What I meant was that if you follow the logic of "computer is in an unknown state. Stop processing everything", then why not continue that to the entire server (operating system, hypervisor, etc.)? Obviously it's not okay in almost any context. Instead, assuming you have something more complicated than a CLI script that's going to immediately exit anyway, you should be handling those sorts of conditions and allowing your event loop/main thread to continue.
