But that's exactly what my improvement to my init.d script does. It 
doesn't wait for an arbitrary delay period, that's the point of my 
improvement. Please take a look at my script, the "stop" code does this:

        $0 stop
        echo -n 'Waiting for MailScanner to die gracefully '
        while ( ps ax | grep -q '[M]ailScanner:' )
        do
          echo -n .
          sleep 1
        done
        echo ' dead.'
        sleep 1
        $0 start
