Thank you!

I wonder what the consequences are in a system that doesn't have
assertions enabled.  Do we just end up with an "upgraded" cached
metapage, and no further ill effects?  That seems pretty benign ...
I hope we don't end up with an expected v4 metapage or something crazy
like that?  (I suppose we would have noticed.)
