How far back in Linux history does that work? It would be bad to remove
instructions needed for versions that people are still using. But yeah,
if we can standardize on describing sysctl that's probably a good thing,
since it applies to more than one platform.

It does make sense for shmall-in-bytes to exceed shmmax-in-bytes, but
probably not by a factor of 4000 ...
