Note this doesn't really work with sshd. The processes handling the
opened connections are still running after a sshd stop. [1]

killall sshd for a quite long time (IIRC this has been fixed). Restart
doing a stop; start sequence, I let you imagine the nice side-effect
this has when doing a restart after a configuration change.
