   * iterators must derived from %_Safe_unordered_container_base publicly, so
   * that safe iterators (which inherit _Safe_iterator_base) can

   * iterators, one for constant local iterators, one for mutable local
   * iterators and a version number that allows very fast
   * invalidation of all iterators that reference the container.
   *
   * This class must ensure that no operation on it may throw an
   * exception, otherwise @a safe containers may fail to provide the
   * exception-safety guarantees required by the C++ standard.
