I know PageRepairFragmentation is real paranoid about this, because I
made it so recently. I suppose it might be worth adding some more
sanity checks to PageAddItem, maybe PageZero (is that ever called on a
pre-existing page?), and PageIndexTupleDelete. Seems like that should
about cover it --- noplace else inserts items on disk pages or
reshuffles disk page contents, AFAIK.
