A way to diff two dumps

[yguedidi]

@BitOne would it be technically possible and make sense to provide a command that does a diff of two dumps made in the same process but at different moments in time?
Have a first dump that will act like a baseline and the second that may contain new objects.

Context: doing batch processing, the is a bootstrapping phase, there I'd dump the first one as the baseline.
Then after each iteration, after the cleanup, I'd dump the second one.
I think ideally it should be equal to the first dump if everything is cleaned up properly, right?
So I want to know if it would be possible to diff the two dumps, to then analyse only on added items, the ones that are likely to leak?
