True enough for the systems which run UNDER VM.  However, as barry pointed
out later in the same article, the once-simple VM has grown an unfortunate
number of features and enhancements.  SO, this means that you get to come
in between 2 and 6 AM to work on VM.

Don't get me wrong--there's still orders of magnitude difference in size
between VM and the systems that run under it, such as MVS.  You DO get some
of the same benefits of a small kernel that you get (?got?) with UNIX.
