Well, not to make things difficult :-), but you _do_ need to use
gtk_container_add(). If you use gtk_scrolled_window_add_with_viewport(),
then you'll have the the following problems:

 - The column titles will scroll with the clist
 - Your CList will be limited to 32,768 pixels in height

I can't really see how this has any relation to threading, but
maybe there is some really funky interaction going on.
