ok, thanks for testing this out, i think i'll integrate this one back 
into the core. (I'm still unsure about the cpu-hog one.) And it saves 
some code-size too:

   text    data     bss     dec     hex filename
  23349    2705      24   26078    65de kernel/sched.o.cfs-v1
  23189    2705      24   25918    653e kernel/sched.o.cfs-before
  23052    2705      24   25781    64b5 kernel/sched.o.cfs-after

  23366    4001      24   27391    6aff kernel/sched.o.vanilla
