Thanks Viktor, that helped reduce the amount of rendering I'm doing.
Unfortunately, I ran into a different problem that I'm not sure is solvable.

        I have two forms, one big one, one little one.
        I use the small partial form to update a div within the big form.
        I then (later) submit the big form.
        I get a stale link because the big form has a different widget count
than it did when originally rendered.

        I think for what I'm doing I'm just not going to be able to use this
implementation of partial form unfortunately. Now that I understand it
better, I can see uses for it, but it doesn't match up well with my use
case.
