         * We reuse a static char. Now hold your breath and listen. This is not
         * wrong and I'll explain why: each component that uses this function
         * is called from the Gtk+ context. The Gtk+ context can never run in
         * parallel with another context because Gtk+ is locked using its
         * gdk_threads_enter/leave lock. This means that there's always at most
         * one thread doing Gtk+ things. This means that this function does not
         * have to be thread safe. And that means that we can have a static 
         * buffer that we'll play with. Else we could also do a pthread_once 
         * or something. 
         *
         * I here the children cry things like: waaayyyy?? Well the reason is to
         * avoid a malloc(). This stuff happens quite often. If we can reuse one
         * buffer each time, that's fine! The GtkTreeView (if this time that is
         * consumer)  makes its own copy. Same for any other Gtk+ component that
         * accepts strings (like a GtkEntry or a GtkLabel). It will make its own
         * copy anyway! If we are going to copy here, that's two copies rather 
         * than just the one copy in Gtk+ that we have no control over.
