Hi Warren, Thanks for the pointer. That quote certainly doesn't describe or justify the very serious corruption bug I'm seeing in any way; however, it seems very likely that the corruption bug was introduced along with this new optimization feature that you reference, so it's good information. If it's indeed the case that this bug was introduced along with this non-essential feature, it would be really good if the feature could be backed out, and possibly re-introduced at a later time after it has been re-worked so that doesn't break the product.
