Indeed, using a series of `#define printf`s might show a little
easier. Everyone being through with `unix II` programming lectures
should however be able to use a combination of dup/pipe constructs,
and seperating the gui from the worker in different process contexts,
well, that's might be better anyway - but again, it requires a good
deal of knowledge on unix process managment and child signaling..., so
it'd be about going to the heart of unix but if this project shall run
non-unix platforms as well (which gtk can do), then... ;-)
