That someone could tweak the knobs up and be able to harvest private
information from set*id cores.  I suppose the counter to that is only
root should be able to do this and if someone is root already... they
don't need to bother with surfing cores for neat stuff, mind you if
they can just get on, tweak the knobs, get off and then just wait for
the cores it may be less noticeable than a root user wandering about
the system.
