Well this is easy to detect and kind of intentionally so, but the broader issue is quite a bit harder. Replace "infinite loop" with some very difficult program that simply takes 30+ seconds to finish and you're back to the same problem.
It doesn't even need to be computationally difficult, you can also slam the memory bus with "far away" fetches that are randomly distributed, ensuring each fetch doesn't share a cache line with any surrounding fetches. There are popular UX effects with basically this workload, even, that's a naive implementation of a large radius gaussian blur basically...
