On machines with real two level memory management, like the 16000, you
don't hve to worry about adding one more segment. In fact, the way to do
it right is to add a segment per module of shared routines. So a program
that uses both termcap and stdio would have at least three text
segments. Simlarly, you could eliminate explicit data i/o by mapping
data segments directly into a process's address spacve. But then, it's
been done, read all about it in Organic's book "The Multics System."
