+1 however... I think there is a corollary

IIRC this is part of the argument Dykstra made with the THE paper years
ago, Parnas in his information hiding paper -- i.e. why microkernels and
proper layering are a good idea. Keep is simple and do one thing
well/protect yourself against other subsystems not being 100%. Linux and
Winders are are bad a the processor.
Yup microkernels are a tad slower and have more overhead, and might
(probably will) cost a little more. But I really do think simplicity
beats complexity and I'll pay a bit in over head to keep it simple.
The problem of course for my employers over the years, is that many people
do not think me
and follow their wallet on the fastest for the cheapest
