Gemstone/S.</div></blockquote></div><br>In Gemstone you also should save changes manually by commit transaction message. But PhantomOS idea is persisting any change automatically. They implement special virtual memory to achieve this. Maybe it is very similar to LOOM as Yoshiki said. I don't know. </div>
