> I think we are losing information about where a key needs to be invalidated when a node changes from owner to non-owner (e.g. because another node joined):
> * We lose the list of requestors stored on this node. Even if all ClusteredGetCommands reached all the current owners (which we are about to change with ISPN-825), once all the current owners leave the new owners will not know about this node's old requestors.
> * We don't add ourselves as a requestor for the key on the new owners when we invalidate the entry and move it to L1.
