Duh.  It also saves you RAM when you're executing multiple programs that use 
the same dynamic library - you only need the library in memory once.  

I wonder if I now get the response comparing to how much memory is taken 
up by an entire library in memory rather than copies of only the routines 
used by the 2+ programs.  Hopefully whoever tries that one will think 
about VM (only the Amiga that I know had dynamic libraries with no VM) 
and how much of the dynamic library will really be in RAM at one time, 
and will also figure out how much swapping will be going on covering the 
routines actually used in the library vs. used in the staticly linked 
programs.  (I have no idea what counterarguments will be offered - 
hopefuly thinking over what I just said will shoot down the stupid ones 
befoe they start...)
