Comment(by ryan):

 As discussed with nacin, the cost this adds is the memory overhead of
 having $wp_roles instantiated for page view for non-logged in users, which
 is most visitors to the site.  It is currently instantiated only for
 logged in users. If we want to avoid this overhead, we can either check if
 the object isset in count_users() and set it if not or move all of the
 isset checks into an _wp_roles_get_object() style function and call that
 function in count_users().
