Comment (by kitchin):

 The proposed patch Attachment 19898.5.diff​ does not work when an
 '''add_action('init', ...)''' callback needs to detect wp-login. In that
 case `@$GLOBALS['pagenow'] == 'wp-login.php'` does work.

 My particular situation is that a plugin author used add_action('init',
 ...) to call session_start(). The session creation is failing due to file
 errors on the server, and I am disabling sessions on the admin side to
 debug.

 > It turns out, we can just use `did_action( 'login_form_login' )` and
 `did_action( 'login_form_register' )`.
