Also toggling a sysctl would require root privileges, but rr does not
currently need to run as root. Thus rr users would have to either
permanently change their system configuration (and every extra
configuration step is a pain), or run rr as root so rr can toggle the
sysctl itself. Running rr as root is highly undesirable.
