The code for bulk insertion currently iterates through the items twice: once when counting them to determine batch size, and once when actually inserting them. This is more-or-less harmless for a List<T> datasource, but is problematic when you're generating items (as I was) via a yield return kind of construct. I don't think that there's any problem with having a batch size larger than the actual batch, so the simplest way to handle it was just to stop the first (counting) iteration.
