+ - use g_main_context_set_poll_func to integrate GTK with GNUnet Scheduler!? (YUCK!)
+ - OR: add scheduler API to enable integration with GTK main loop instead of doing our own select
+ - use g_main_context_pending, g_main_context_query / g_main_context_check / g_main_context_dispatch
+ and NEVER g_main_loop_run (can this be done? might be the clean way to do this! But how
+ to integrate this with "gtk_main"? Docu says:
+ "It's OK to use the GLib main loop directly instead of gtk_main(), though it involves
+ slightly more typing. See GMainLoop in the GLib documentation."
+ => so maybe it "just works"?
+* SETUP:
+ - design & implement new setup tool
