Preemptibility is an optional kernel design feature. Not all kernels have it and not in all ways. If it's intentionally designed that way it's not a bug. No kernel stops users from filling up disks (though some filesystems have such limits as features, which most of us turn off) Pretty much the only kernels that are totally preemptible are RTOS and they still don't stop you from shooting yourself in the foot.
