Sorry for the differing suggestions on our part.  I think Kim's point
was to not have the accessors.   I vote to (1) keep the accessors (which
are currently there) and  use (2)

> BlockFreelist *dictionary() { return &_dictionary; }

and the style dictionary()->XXX (to minimize changes).


How about we let Jungwoo integrate with the style (1) and
(2) I outline above so he is not caught in the middle.  You
and I can talk about it on the side.
