% The AIX v3 kernel is pagable. It is divided into three "segments", as

% object code - that is, text and data ]

% The various system tables are defined with huge sizes, and the system

% them, thus ending the dilema about creating new proc table or whateve
% entries by rebuilding the system. On a typical system the size of the
% kernel is somewheres near 20MB, much of which is never even used - it
% just remains off in virtual la-la land waiting to be referenced ...
But the tables still require page space, right? V.4's dynamically-sized
tables sound like a better idea.
