Comment:

 This problem is still affecting me, when programmatically spawning terms
 and specifying parents with wp_insert_term()

 {{{
 $kid_term = wp_insert_term( $kid, $taxonomy, array( 'parent'=> $parent_id,
 'slug'=> sanitize_title($kid) ) );
 }}}

 I can see the terms in the DB, and in wp_term_taxonomy table their parent
 *is* set, but the wp_option table items for {taxonomy}_children is stuck
 on an empty array.

 wp_insert_term() includes a call to clean_term_cache(), but if it's doing
 anything, it's still not updating the {taxonomy}_children field.

 If I manually (through the wp_admin interface) set a term to have a
 parent, the option gets updated and displays correctly.

 I've even included a call to clean_term_cache() after all my
 wp_insert_term() calls are done - still nothing.

 HOWEVER - if I go and delete one my terms in the wp_admin interface, the
 option gets updated - and of course clean_term_cache() is called in
 wp_delete_term() - so sometimes it's doing it's job and sometimes it's
 not....
