There is a lot of truth to that. While I agree that high load is a
actually a good thing, some programs like sendmail change their behaviour
based on load and do strange things like stop accepting new mail. _People_
are even worse thise way - their blod pressure rises with load :-). It
almost seems that some sort of a ficticious reading of a load inside a
context would be benificial.
