Not sure I get what you mean by node-local data.  Are you assuming a view of global state that is locally resident on a node in question?  If so, double-counting may still happen if the task ends up on 2 nodes, both of which happen to own an entry.

Two nodes can own the same entry? We can always us CH to find primary owner, right?!

Ok true. Time permitting. Maybe we get some help from the community as well ;)
