1. 5.3 modules/hs_taxonomy.module \_hs_taxonomy_hierarchical_select_get_tree()
2. 7.3 modules/hs_taxonomy.module \_hs_taxonomy_hierarchical_select_get_tree()

Drupal core's taxonomy_get_tree() doesn't allow us to reset the cached trees, which obviously causes problems when you create new items between two calls to it.
