+The #GtkListStore can accept most GObject types as a column type, though
+it can't accept all custom types.  Internally, it will keep a copy of
+data passed in (such as a string or a boxed pointer).  Columns that
+accept #GObject<!-- -->s are handled a little differently.  The
+#GtkListStore will keep a reference to the object instead of copying the
+value.  As a result, if the object is modified, it is up to the
+application writer to call @gtk_tree_model_row_changed to emit the
+"row_changed" signal.  This most commonly effects lists with
+#GdkPixbuf<!-- -->s stored.

+Internally, the #GtkListStore is implemented with a linked list with a
+tail pointer.  As a result, it is fast at data insertion and deletion,
+and not as fast at random data access.  The #GtkListStore sets the
+#GTK_TREE_MODEL_ITERS_PERSIST flag, which means that #GtkTreeIter<!--
+-->s can be cached while the row exists.  Thus, if access to a
+particular row is needed often, it is worth keeping the iter around.
