I don't think we are making any promises in terms of debug-mode performance. Is
it better for other debug-mode implementations doing checks of similar
strength?
Maybe Francois has ideas, adding him in CC. If I remember correctly, in some
cases we have been able to make progress rather easily by simply going to
unchecked iterators before forwarding to internal implementation details.
