It seems. But i think it could be used to make the launch_media_server call 
wait 
or not for the launch completion. 
My current problem is waiting for the media_server launch completion, i tried 
to 
send it a message with some timeout (2 seconds for deliver, 2 seconds for reply)
, but it answers very quickly. What should i do ? I think media_server should 
postpone its reply until launch completion. Is it a good practice ?

Yes, it seems a good pseudo code. It's just the notifications in media server 
seem not implemented. So feeding the port should be tricky. We could start with 
a thread with several snooze calls though :)
