Comment(by misterbisson):

 A note on performance: this could be made faster yet if the terms were
 resolved to `term_taxonomy_id`s and only the the `term_relationships`
 table was joined. The difficulty there is with `get_term_children()` which
 expects and returns only `term_id`s.

 Adding this patch, however, is a good stepping stone to further
 optimizations.
