Good point, I think that would work.

Well, GUI_impl.h isn't installed...

Also, I suppose that there's no real requirement that it is a singleton. I 
just want the library to provide a ready-made global so that I don't have 
to create it in every program. Multiple GUIs could work in principle...

Also, I probably forgot to do it.

Also, it seems that we have two commandline interfaces at the moment 
(closely related). I'll probably remove mine, but I might well modify 
yours.

I like the process_in_crnt_thread() methods, since they make all the wierd 
segfaults magically disappear...
