When updating the alias through pathauto_taxonomy_term_update_alias() it uses taxonomy_get_tree(), which will load the entire vocabulary. When dealing with vocabularies with many terms, this will add a very heavy load, both CPU, DB and memory, and may even cause memory limit breaks. Using taxonomy_get_children() fixes this.

This seems like a smart change for sites with many terms.

Would there be a regression if you have more than 2 levels as I think that only get's the direct children?

Why aren't we using $term->vid as the second parameter here?

Re #6: I think you're right. Current code sets 'alias children' to FALSE before recursive call because it already gets all levels from taxonomy_get_tree(). Here's a patch that doesn't set 'alias children'.

Re #7: I don't know but I guess we can add that since taxonomy_get_tree() also returned terms by $term->vid.

Note that taxonomy_get_children() always loads entities while taxonomy_get_tree() didn't.
