Sure, today's CPUs execute not only in parallel but also out-of-order. But that doesn't matter since threads don't let threads die before they've done their share. Out-of-order makes thread synchronization a little harder (when implementing lock-free algorithms for example), but that has nothing to do with exceptions.
