extremely expensive. you would have to...
- assemble a list of all objects IDs in the ZODB
- parse all contents of all objects and check against that ID list.
you would probably need a little counter for every single ID that gets
incremented upon finding its ID referenced, and all those that are left
over with the counter at 0 in the end would probably be candidates for
this schema will fall down the moment your object IDs are not unique
across the whole ZODB. besides, every object is potentially different
in how you access and read its "contents".
if your whole intent is to have a "cleaner ZODB" and there is no
pressing reason to do this cleanup, i would just forget about it.
