In general that status part of the init scripts deserves some fixing too. The 
problem is that this status checks whether the service is supposed to be 
running, not whether it is actually running. If we were to implement a status 
function we could use that for the restart too (only start when the status 
returns that it is actually not running anymore, or after a predetermined 
time has passed, say 10 seconds)
