How does this "smart linker" business tie into the "shared libraries"
in Unix V.3.  As I understand it, (1) when I need a module, the whole
library is loaded, but (2) when another program needs a module from
the library, it shares the core image that is already in memory.

So, for example, at any moment, there is only one copy of all the stdio
(that's standard input-output in Unix-speak) stuff in memory at any given
moment, and all programs that need it share.  (This also makes the
executables smaller and saves disk space and load time.)

                                     Just asking,       Lee
