Comment (by jnylen0):

 Should the `adjacent_posts_rel_link_wp_head` function be marked as
 deprecated also? I don't see that it's used anywhere else.

 Also just a note for others following this ticket, enabling memcached or
 another object caching solution will help this performance issue
 significantly, since the `get_adjacent_post` function uses `wp_cache_set`
 and `wp_cache_get` appropriately.
