I think what he is after is shared libraries.  Even though shared text
segments occurs in most UNICES, many programs contain a substantial
number of library routines that are common to programs that are not
loaded from the same disk file.  Other operating systems have provision
to keep library routines in memory so only one copy exists even though
their may be many different programs using them.
