match DSets and setting attributes. With the old behvaior, if a client subscribed to a DObject and modified an OidList on it in a single pass, it could miss the modification. The DObject is serialized immediately when the server gets the subscription request, but events aren't sent for that subscription till it's processed the next time the omgr queue comes round. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@6420 542714f4-19e9-0310-aa3c-eee0fc999fb1
