--------------------------+-----------------------------
 While using ALTERNATE_WP_CRON, there is a redirect to a modified url
 including doing_wp_cron whenever a cron must be performed.

 A condition prevents the redirection from happening on POST, but when an
 xmlrpc is posted, the guard (!empty($_POST)) fails to prevent the
 redirection because the content does not get parsed into $_POST.

 In cron.php, spawn_cron, I propose replacing
 {{{
 function spawn_cron( $gmt_time = 0 ) {
 ...
         if ( defined('ALTERNATE_WP_CRON') && ALTERNATE_WP_CRON ) {

                 if ( !empty($_POST) || defined('DOING_AJAX') )
                     return;
 }}}

 by

 {{{
 function spawn_cron( $gmt_time = 0 ) {
 ...
         if ( defined('ALTERNATE_WP_CRON') && ALTERNATE_WP_CRON ) {

                 if ( 'POST' == $_SERVER['REQUEST_METHOD'] ||
 defined('DOING_AJAX') )
                     return;
 }}}
