Note that this is true of both shm AND /dev/zero.
Whether it is done in the current really clunky manner (ugly special shm
tables) or in the RightWay(tm) (page cache), shm and /dev/zero should
always basically be the same. The only difference between shm and
/dev/zero is how you access and set up mappings, not how the actual
mapping then works.
