yes, this is if the hard scheduler is actually enabled


That's one I forgot to mention - none of this has any visible effect (and by that I mean inability to drive the load to 30) unless sched_hard flag is set.

A load of 30 is not a real problem (in terms of CPU, anyway)

...

So all you're doing is hiding the problem and underutilising your CPUs.

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.
