Both maintaining the map items inside the Synthesis engine and storing them in .ini hash config nodes inside SyncEvolution are fairly heavy operations which are not needed at all during an ephemeral sync (= no meta data stored, done by the PIM Manager when triggering a pure PBAP sync). Using the new Synthesis CA_ResumeSupported DB capability it is possible to suppress these operations without having to fiddle with the Synthesis DB API that SyncEvolution provides. To make it possible at the DB layer to detect that the meta data is not needed, the ConfigNode passed to it must be marked as volatile. This change sped up a sync with 10000 unmodified, known items from 38s to 23s.
