I had windows do a large update in the middle of an exam once. Like the major version number changes or something, took probably like an hour and a half. I was quite lucky with the exact timing and the fact that I am usually able to finish exams quickly as I did end up having half an hour for the exam, but it did make the whole situation a bit more spicy than necessary.
Or in other words, the thing you keep quoting does not apply in this case. Any number divided by zero is undefined, not positive infinity (or negative infinity for that matter).
