lolsome, libraries are here to avoid code duplication in memory,
i know that most of GNU ones are blobs, but the solution is not coding
like gcc -static does. This is a task of the compiler and what you're
proposing is a bad software design rule.

About the shared object loading..it's not inside libC on GNU systems.
This task is delegated to libdl. so it's an standalone library.

I think that system elf loader (ld.so) should be able to do it so..if
you're writing a virus or playing with low-level stuff on *nix you can
get a look on it.

This will make dwm unportable and we should implement the different
ways to communicate with X11 (socket file, network,..)
