 process_default_headers currently hits get_template_directory_uri() and
 get_stylesheet_directory_uri() twice per default header. Considering there
 are filters on these functions' return values which could potentially be
 costly, and we expect the values to not change, it makes sense to store
 them locally once before the loop.
