I can't really believe this works well. Well, maybe if the application is
build so that Linux knows right what code is used, but for example
netscape and kde, why do they take so much memory and don't work well
with computers with low memory? They use all their code and do "if
(!do_i_need_to_do_something()) return" type things everywhere? I don't
know, but I'm sure I haven't used any sounds and still KDE's sound servers
eat megs of memory.

Shared libs are loaded entirely to memory or just parts of them? (should
some of them be divided into smaller libs?) And do you mean that they are
not even loaded or that they are loaded to memory and possibly placed to 
swap?

Well, at least you need to have some wrapper functions because you can't 
directly use gtk_() functions.. ok, not much :) And I don't know about
gmc's code but I just had some feeling that if program works in text mode,
X, windows, etc, it must have useless code..

But my swap gets full... ;)
