Separately, but relevant in particular to the above due to the
potential for races:  what is the defined behaviour when diffing
against a live filesystem (rather than a snapshot)? 

is there an implied snapshot (ie, diff based on content frozen at
txg_id when started) or is thhe comparison done against a moving
target? 

It's not just a question of implementation if it can affect the
output, especially if it can make it internally inconsistent.
