If it's several copies of the same program, shared libraries won't save you
anything because the programs shar text anyway (i.e. if you have 10 vi's 
running and vi has a size of 125k text, 136k data the total memory resources
will be approximately 125k + 10*136k. This is the same even if vi is compiled
with shared libraries).

The place where shared libraries save you is when you have multiple programs
that use the same libraries, since different programs do not share text (unless,
of course, you set up the programs as links to each other and used argv[0]
to differentiate between the two - like mv/cp/ln).
