cron error with ALTERNATE_WP_CRON set to true

[luis.ferro]

If you turn on ALTERNATE_WP_CRON on a stock WP 3.2.1 you will get an error of undefined function wp_redirect() in cron.php.

This is due to the order of includes in wp-settings.php which is wrong in this use-case.

An include on the top to the effect of:

require_once( ABSPATH . WPINC . '/pluggable.php' );

will sort it out (please be sure to either change the bottom require to require_once, or remove it altogether).

Blocker, because it breaks functionality.

Tested on stock 3.2.1 with no plugin active.

Cannot reproduce.

spawn_cron() is called by wp_cron() which is hooked into the sanitize_comment_cookies which is fired after loading pluggable.php.
