Comment:

 The performance differences are not huge. I jury-rigged a database so that
 `parent_dropdown()` would generate about 10,000 items. Execution time and
 memory footprint with [attachment:17026.2.diff] are maybe 10-15% more than
 the direct query. I squeezed a little extra performance out with
 no_found_rows=true and by turning off cache priming for terms/meta.
