sshd and daemontools

[george]

Hi there,
  I tried to use an supervise in daemontoos
(ftp://koobera.math.uic.edu/www/software.html) to monitor the sshd daemon
so that it will start the daemon if it dies. But it keeped starting it and
I get the following messages continuesly until I kill it:

Starting sshd...FATAL: Creating listener failed: port 22 probably already
in use!
.....
  
  Here is my script:

PROG=sshd
LKDIR=/var/lock/sshd

mkdirs() {
    [ -d $LKDIR ] || ( mkdir -p $LKDIR );
}

start () {
  mkdirs
  echo -n "Starting $PROG..."
  supervise $LKDIR /usr/local/sbin/$PROG  
  echo "done"
}
 
  Anyone saw this problem before? Thanks for any hints.
