Actually, that might not be such a bad idea, now that I've pondered on it some
more.  Give it an array of iterators and add a flag to each iterator to say if
it can be spliced from or not.

Once ITER_PIPE is killed off, advancing and reverting over it should be pretty
straightforward - though each iterator would also need to keep track of how
big it started off as in order that it can be reverted over.
