That's something the distro's need to do (and they are already doing it, 
AFAIK)... but it's a fact that due to the usage of the kdeinit fork hack,
that most binaries export way more symbols than necessary. (default with 
GCC+ELF is that everything is exported).

GCC 3.4.2 finally has an option to change the default to hidden. A while 
ago I changed my KDE to only export what was needed.. but I didn't get too 
much reponse on the patch, so I stopped working on it.

Anyway.. I haven't followed the lastest changes to KDE, but if I'm not 
mistaken, the QKW work is making this symbol hiding possible for ELF too.

You did... it only madvise()'es the PT_LOAD sections of the binaries.
