art "virtual memory" (whether
 as segments or as pages) has been defined since it was first conceived?
 Virtual addressing is necessary for virtual memory.  The converse is not
 true. 
Well, it is obviously not a definition DEC agrees with, so I guess that
means there are two different schools (atleast) here.
And when talking about the VAX (which this thread started with), it
might be meaningful to use DEC's definition?
