Comment(by dd32):

 I was originally going to add this to the metabox:
 {{{
 $name = ( $taxonomy == 'category' ) ? 'post_category' : 'tax_input[' .
 $taxonomy . ']';
 echo "<input type='hidden' name='{$name}[]' value='0' />"; // Allows for
 an empty term set to be sent. 0 is an invalid Term ID.
 }}}

 That'd have worked and done the job..

 But handling it properly in wp_insert_post() is probably better.

 {{{
 if ( isset($tax_input[$tax_name]) )
     $term = $tax_input[$tax_name];
 elseif ( $tax_obj->show_ui )
     $term = array();
 else
     continue;
 }}}

 I dont like that for one particlar reason, tax_input will only be set by
 show_ui, if a plugin sets it itself with a custom div, then they'll have
 to hack around this bug themselves by including a 0 term_id.

 Its probably best to have a clear-cut working functionality, Any
 automatically added metaboxes will work as expected, but if a plugin adds
 a custom taxonomy div, they'll have to handle all the term saving..

 This is a version i've come up with based off scribu's patch:
 {{{
         // new-style support for all taxonomies
         $tax_names = get_object_taxonomies( get_post($post_ID) );
         foreach ( (array)$tax_names as $taxonomy ) {
                 $taxonomy_obj = get_taxonomy($taxonomy);
                 if ( !current_user_can($taxonomy_obj->show_ui) )
                         continue;
                 if ( !current_user_can($taxonomy_obj->assign_cap) )
                         continue;

                 $tags = isset($tax_input[$taxonomy]) ?
 $tax_input[$taxonomy] : array();
                 wp_set_post_terms( $post_ID, $tags, $taxonomy );
         }
 }}}
