Actually I might be wrong about iterators for GtkListStore.

GtkListStore uses a GSequence internally, and it stores a GSequenceIter
in the GtkTreeIter.user_data field.  GSequenceIter is supposedly stable;
it remains valid even after the GSequence is sorted.

So maybe GtkTreeIters -would- work for the hash table index using
gtk_tree_iter_copy() and gtk_tree_iter_free().  I'll do some further
testing to verify.

Again this would only work for GtkListStore, but that still covers the
majority of cases if I recall correctly.
