I do not believe this is possible. The addition isn't adding additional
changes, it's *preventing* additional changes. We can't create a second query
that prevents updates caused by the first one.

I think we have only two choices here, either accept the speed cost or switch
back to the original version. I have no problem with either choice, but one
must be made. We can't hold this feature in discussion forever. This is not
complicated as a choice, especially since it seems that the speed cost is
unacceptable.
