Thanks for your comment, Mike.

I forgot to do that. So I prepared new patch series
to implement your suggestion.

The new patch series containts new benchmark program,
based on Ingo's pipe-test-1m.c
http://people.redhat.com/mingo/cfs-scheduler/tools/pipe-test-1m.c

And the series became too big to pack into one mail.
So I'll send it in new thread. Please wait a minute.
