Warning! This guy is kidding!
My notebook wouldn't be what it is without shared libs. (Great work,
Paul K.!) Especially for X programs, the improvement is considerable.
A simple `xlogo', statically linked, consumes half a megabyte! Linked
shared, it's 8 K.
Not only they save disk space, they also save physical RAM pages.
Every X application needs the Xlib, and almost every the Xt lib. It's
just obvious that it's better to have this half meg loaded once only,
instead of paged in/out with every context switch between the appl's.
Of course, it does make a larger difference it your machine has only 5
MB of RAM, and not 16 :)

Never test for an error condition you don't know how to handle.
