 refresh_user_details() potentially leaves garbage in the cache, in that it
 merely deletes two buckets:

  - users
  - userlogins

 wp_delete_user(), by contrast, additionally deletes:

  - useremail
  - userslugs

 There are several other occurrences where the same applies, in WP. We
 should refactor the area of WP a little and introduce some kind of
 clean_user_cache() function.
