re: remove the need for the snapshot iterators then? Yes, mostly. There's one other use for those iterators, I think - they can in unusual circumstances, speed things up (but mostly, they slow things down a little). The speed up happens if you're doing a fully sorted index with lots of subtypes interleaved and do multiple moves forwards and backwards. The snapshot "flattens" the interleaved nature (if I remember correctly), and then the forwards and backwards movement occurs more efficiently, without "rattling" the multiple iterators (one per type) as they interleave.
