Just to play devil's advocate, why use the processor to address persistent, shared data objects? The processor is designed to address objects that live in volotile store, exist for the lifetime of a process, and are private to that process. The database engine is designed to address persistent, shared, objects. The database engine uses processors, but it doesn't depend on particular processor's address space.
