Can use shm_open and mmap to get POSIX standard shm behaviour via a sane
interface without adding more crap to the sys3 shm madness.

Sorry this patch is completely bogus - introduce the user programs
involved to 1990s technology. They have to be updated to use such a
change as is proposed anyway so they might as well use shm_open/mmap at
which point no kernel changes are needed.
