 An endless loop of upgrade can happen.
 It seems the cause is the test in wp_upgrade()

 {{{
         if ( $wp_db_version == $wp_current_db_version )
                 return;
 }}}

 While the test in admin.php is :
 {{{
 if ( get_option('db_version') != $wp_db_version ) {
         wp_redirect(admin_url('upgrade.php?_wp_http_referer=' .
 urlencode(stripslashes($_SERVER['REQUEST_URI']))));
         exit;
 }
 }}}

 I just got a WP2.7 install with
 {{{
 // in upgrade.php
 echo "<br />$wp_db_version == $wp_current_db_version";
 // > 9872 == 9872
 }}}
 so the upgrade process never take place
 but
 {{{
 // in admin.php
 echo get_option('db_version') .' != '.$wp_db_version;
 // > 9771 != 9872
 }}}
 always redirect
