Use g_timeout_add_seconds_full() for the timed poll of the storage file,

Browse Source 
2007-06-19  Emmanuele Bassi  <ebassi@gnome.org>

	* gtk/gtkrecentmanager.c: Use g_timeout_add_seconds_full() for
	the timed poll of the storage file, since we are using multiple
	seconds intervals and we don't actually care about millisecond
	precision.

	(threads_dispatch), (threads_free), (gtk_recent_manager_init),
	(gtk_recent_manager_set_filename): Roll our own version of
	gdk_threads_add_timeout() using g_timeout_add_seconds_full()
	while holding the GDK main lock.
