ra�Like SyncManager but uses SharedMemoryServer instead of Server.

        It provides methods for creating and returning SharedMemory instances
        and for creating a list-like object (ShareableList) backed by shared
        memory.  It also provides methods that create and return Proxy Objects
        that support synchronization across processes (i.e. multi-process-safe
        locks and semaphores).
