 Any delete_* action should be preceded by a can_delete_* filter to allow
 plugins to prevent deletion of ... stuff. And:
 if(apply_filters('can_delete_user', true, $user_ID) == false) return
 false;

 E.g.: I have a plugin that deletes users who have no logged in for 3
 months. But when I issue wp_delete_user I want to allow other plugins to
 prevent deletion. Let's say that user has bought something from my blog. I
 want to keep it even if administrator tries to delete it.

 This way ... if I choose 50 users to delete I could just internally skip
 those un-deletable. I know I can wp_die when I don't want to delete a user
 [on delete_user] but I'd rather protect the user silently than having to
 delete again after de-selecting that user from the selection.

 E.g.: Inside wp_delete_user ... instead of:

 {{{
 do_action('delete_user', $id);
 }}}
 set:
 {{{
 if(!apply_filters('can_delete_user', true, $id)) return false;
 do_action('delete_user', $id);
 }}}

 PS: Hope I make any sense.
