mythtv-backend: init restart unreliable [patch]

Hi Christian,

I noticed '/etc/init.d/mythtv-backend restart' is unreliable.

This is due to the 'sleep 3' solution between stop/start via
start-stop-daemon; this is not sufficient for my setup, so in most
cases, myth is just stopped on restart as the second start-stop call
still finds a valid pid.

start-stop's "-retry" should imho fix this quite elegantly, see
attachment.

Thanks!

Stephan
