Meanwhile, in the real world, it is exactly what we need at work. Anonymous shared memory (MAP_ANON and /dev/zero) isn't good enough. Actually, we dont care for the shm_open() API too much at all since it conflicts with our application libraries. Fortunately it doesn't exist in 4.x yet, which is where we need the persistent object thing anyway.
