hide/disable sidebar in Twenty Ten child theme

I’m making a twentyten child theme and I’m customizing the following:
style.css
footer.php
header.php
index.php
loop.php
sidebar.php

I got rid of:
<?php get_sidebar(); ?>
in index.php
but something is still calling the default sidebar.php

Is there a neat trick to get the page to output a list of each template file that is used to construct the current page?
