  {
    // to trigger duplicate unique ids in the old code, you needed the following circumstances:
    // The single mesh generation routine (e.g. build_cube) *must* add a node after all the elements
    // such that it is not an element that has the largest unique id in the single mesh. (build_cube
    // with TET10 adds a node after all the elements are added because it calls all_second_order
    // after all the elements are created.) If an element has the highest unique id, then the final
    // value for _next_unique_id was (and still is) correct at the end of copy_nodes_and_elements
    // because we set the element unique ids before adding the elements into the original mesh, such
    // that _next_unique_id gets correctly updated. But when a node has the highest unique id, then
    // _next_unique_id would be incorrect with the old code (but is now correct with the new code!)
    // and after one mesh collection the value of parallel_max_unique_id() would be conceptually
    // wrong, such that the next time we collected a mesh we would be at risk of duplicating unique
    // ids
