You are quite right, state dumps don't help if most of the objects that
are part of the mud's state are garbage.  Apart from state dumps, you
also need the discipline to clean up such garbage, or not to create it
in the first place.  This is actually accepted practise in any type of
mud other than LPmud.  In such muds, running out of memory due to too
many garbage objects is a disaster that would not just cause a reboot,
but would put a permanent stop to the mud itself -- unless there is an
old statedump to restore from.
