"iters-persist" is used to indicate whether TreeIters are guaranteed to 
be valid for as long as the node they refer to is valid (like 
GtkTreeStore and GtkListStore).  Sometimes models have iterators that 
aren't valid after signals, etc., so their "iters-persist" flag is 
false.  (I think) models should also start using a new stamp when 
existing iterators become invalid, so they can detect when someone 
passes them an invalid one.

Hope this helps :o)
