I am not sure I understand your problem.
If entities are in a set, you should remove them from the set, before deleting the entities.
If this is too hard, when you create the set you should use the MESHSET_TRACK_OWNER flag.
In that case, removing from the set is managed automatically when you delete the entity (this takes more memory, and it is not turned on by default). Do you create sets?

I am not sure about the sharing part, but I think that you would need to manage that yourself; the distribution/sharing is resolved at the beginning; 
Still, what is the scenario?
