The problem with iterators is that they are static with respect to the
container.  What I need is a real queue with real queue action (i.e.
item insert and removal) but with some bounds on queue size.   Unless
the iterator keeps a reference to the container, it can't do this.  If
it does keep such a reference, I don't think it's really an iterator
anymore.

Thanks for the reference.  I'll have a look.
