Well, I've changed my code in about 6 different places now, and in fact, it is exceptionally simple to change from my code to add the "DELETED() as deletedrec" field and use that field rather than the deleted tag. In the end the code is almost identical to what I was doing, so the change was easy.

It works well, and the worst one takes maybe a full second.
