This behaviour is semi-reasonble: Axiom creators treated Axiom and
supporting programs as an Internet server where clients come, request
some computation and go away while the core parts (AXIOMsys, sman,
session, viewman, nagman) run for long time.
Anyway, if you look for design flaws, you will probably find many.
One example that I found few days ago: 'AXIOMsys' at various moments
sends 'EndOfOutput' command to 'session' and then go on to process
information sent by 'session'. But session also sends commands
to 'AXIOMsys' and for some commands expects that 'AXIOMsys' will
return some data as an answer. There were no way for 'session'
to distinguish returned data from 'EndOfOutput' command.
