I have question about FSM structure on the page. If I look into the code it
seems to me that tree structure is "degenerated" on the right side. It is
probably space optimization because complete tree needs BLCKSZ/2 space on the
page and rest is empty.

Is my assumption correct? If yes maybe extra note in fsm_internal.h about it
could be helpful.
