 Using Memcached Object Cache

 This works for me right away in trunk:

 {{{
 php -r "require 'wp-load.php'; echo get_permalink(1); switch_to_blog(2);
 echo get_permalink(1);"
 }}}

 The more advanced use case also works right away:

 {{{
 // post with ID #10 exists in both blogs

 wp_insert_post( array( 'post_title' => 'Cash Money', 'ID' => 10,
 'post_status' => 'publish' ) );
 switch_to_blog( 2 );
 wp_insert_post( array( 'post_title' => 'Money Cash', 'ID' => 10,
 'post_status' => 'publish' ) );
 switch_to_blog( 1 );
 get_post( 10 );
 restore_current_blog();
 wp_update_post( array( 'post_title' => 'Cache Money', 'ID' => 10 ) );
 $z = get_post( 10 );
 echo $z->post_title . PHP_EOL;
 switch_to_blog( 1 );
 $z = get_post( 10 );
 echo $z->post_title . PHP_EOL;
 switch_to_blog( 2 );
 $z = get_post( 10 );
 echo $z->post_title . PHP_EOL;
 exit();
 }}}

 I think these problems pre-date all of the switch_to_blog work Ryan has
 done recently: [21485], #21595, [21628], [21403], #21434
