Query_posts infinite loop?

Could anybody tell me why this is looping infinitely?

<?php get_header(); ?>

<div id="content">
  <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
  <div class="post" id="post-<?php the_ID(); ?>">
    <h2>
      <?php the_title(); ?>
    </h2>
    <small><?php the_time(__('M jS, Y','branfordmagazine')); ?> | <?php _e('By','branfordmagazine');?> <?php the_author_posts_link('namefl');?>
	<?php edit_post_link('Edit', ' | ', ''); ?>
    </small>
    <div class="entry">
       <?php the_content("<p class=\"serif\">" . __('Read the rest of this page', 'branfordmagazine') ." &raquo;
"); ?>

      <?php wp_link_pages("<strong>" . __('Pages', 'branfordmagazine') . ":</strong>", '
', __('number','branfordmagazine')); ?>
    </div>

  <?php comments_template(); ?>

  <?php endwhile; else: ?>
  <?php endif; ?>

  <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
	  <?php $taglist = get_the_tags(); ?>
	  <?php $tagcount = 0;?>
	  <?php foreach($taglist as $taglists){
		if ($tagcount == 0){
			$myposts0 = query_posts("tag=VAMP&showposts=1");
			$tagcount++;
		}
		elseif ($tagcount == 1){
			$myposts1 = query_posts("tag=DYMAX&showposts=1");
			$tagcount++;
		}
		elseif ($tagcount == 2){
			$myposts2 = query_posts("tag=DGA&showposts=1");
			$tagcount++;
		}
		else{
			break;
		}
	 };
	  ?>

	  <div id="lefttag">
		<ul>
		<?php foreach($myposts0 as $mpost0) { ?>
			<li><a href="<?php echo get_permalink($mpost0->ID); ?>"> <?php echo $mpost0->post_title; ?></a></li>
		<? } ?>
		</ul>
	  </div>

	  <div id="middletag">
		<ul>
		<?php foreach($myposts1 as $mpost1) {?>
			<li><a href="<?php echo get_permalink($mpost1->ID); ?>"> <?php echo $mpost1->post_title; ?></a></li>
		<? } ?>
		</ul>
	  </div>

	  <div id="righttag">
		<ul>
		<?php foreach($myposts2 as $mpost2) {?>
			<li><a href="<?php echo get_permalink($mpost2->ID); ?>"> <?php echo $mpost2->post_title; ?></a></li>
		<? } ?>
		</ul>
	  </div>

	  <?php endwhile; else: ?>
	  <?php endif; ?>

</div>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

it shows up as
bullet – post
bullet – post… infinitely
