Yep, remember, this was back in the era when multitasking was a mainframe word and was unheard of on anything smaller than room sized. Even then, multitasking was very limited and most commercial mainframes still required a human (or sub-human) operator to manage the workload. Personal Computers didn't get multitasking until the Macintosh came out and even then it was cooperative multitasking (software based) rather than preemptive multitasking (hardware based) and your infinite loop really would bring the machine to it's knees.
