 [attachment:18785.diff] reworks how WP_Screen stores data. Everything ends
 up in private and static variables. Keeps full compatibility and since
 everything is encapsulated, we can optionally create a formal factory

 convert_to_screen() can return a new WP_Screen object now, even for the
 current screen's ID. Data does not die when a reference to an object is

 The global in get_column_headers() is now just a static.
 $_wp_contextual_help is gone now too, though the back compat filters
 remain. It is now WP_Screen::$_old_compat_help.

 There's some more cleanup to be had here, but it's in good shape. If
 anyone else has something to propose, please provide a patch and comment.

 I intend to close this as fixed before beta 2.
