Comment:

 I *think* that this:

 {{{
 wp_cache_set( 'get_pages', $cache, 'posts' );
 }}}

 ... is needed.

 what is missing and may not necessarily be needed is:

 {{{
 update_post_cache($pages);
 }}}

 that being said, adding such a call will tremendously speed things up when
 generating permalinks, since it saves one query per missed cache hit.

 maybe there is a need for an extra cache group, for use by permalinks.
