Well, that would work in sort of preventing a complete lockup, but the watchdog wouldn't even know if the task eating lots of CPU is privileged (OK) or unprivileged (not OK). Also, the original RLIMIT_RT_CPU feature allowed you to really control how much CPU is available to unprivileged users, not just prevent them from getting 100% CPU.
