In this other approach, the iterators of the stable_vector would really be
the linked list iterators, and the vector would only be used to get random
access. Actually... now that I think about it, that would give you random
access with stable_vector::operator[], but not
stable_vector::iterator::operator[], yuk. I think acheiving iterator
stability in this case may not be worth while.
