This really has nothing to do w/ workload but rather w/ multi-user processing 
/tasking /threading.  And the mere fact that the 2.6 kernel prefers 
kernel-threads should imply an overall performance increase (think pdflush).

The reason why not many have noticed this scheduler problem(s) is because 
most hackers nowadays work w/ the latest fastest hw available which does not 
allow them to see these problems (think Windows, where most problems are 
resolved by buying the latest hw).

Real Hackers never miss out on making their work run on the smallest common 
denominator (think i386dx :).

Thanks!
