i didn't see such conclusion.

Simon Burge suggested to make it optional.  and i answered that
i don't think it's worth to be optional and it's a first step to
make vnode allocation more dynamically.  then the discussion came to an end.
so i thought that he had been convinced.

matthew green once expressed a doubt about its worth.
but he said a positive comment (privately) after that.  then i thought that
he had changed his mind.

Bill Studenmund suggested "heavyly-poolify" approach.
afaik, what i committed isn't conflict with his idea.

i can't recall any other objections.

please correct me if i'm wrong.
(actually, i'm often wrong esp. when talking in english... sorry)
