 6.  How do I use GTK with threads?
 
     GTK requires that all GTK API calls are made from the same thread in which
-    gtk_init() was called (the _main thread_).

     If you want to take advantage of multi-threading in a GTK application,
     it is usually best to send long-running tasks to worker threads, and feed
