 clicking the publish comment button won't output two comments.

 Yes, I think that's it's main purpose too.

 Adding a unique ID for each comment, that gets passed into the comment
 form, and that expires upon the comment being saved, would easily defeat
 this (it would probably cut a lot of spam, too). The duplicate-comment
 check could then be rendered obsolete, in favor of redirecting to the
 newly published comment itself.

 The unique ID could use a mechanism similar to post-new.php that assigns a
 neggative ID to a post, before it is saved.

 Also, this plugin implements a similar technique:
