I could care less what man pages say, I'm saying THATS NOT HOW IT WORKS.
Linux has *ALWAYS* worked this way. Load Average is measuring something
completely different than your 'r' and 'b' in vmstat. Presumably, there
are far more processes in 'interruptable sleep' than 'uninterruptable
sleep', and vmstat doesn't seem to count these.
