in R5 launch_media_server sends a BMessage through a BMessenger with the 
signature of media_server with these timeout settings. i don't know exactly 
media_server  does with it. It should receive the message and handle it. It 
can't block its loop until the launch is completed, maybe it sets up a 
BMessageRunner to submit again the BMessage for handling it again later when 
launch is complete. I don't know either when we can say the launch is complete. 
I should take a look at what notifications do exactly.

I'm not sure about the easiness. Do you mean there should be a mean to set the 
reply port and then B_QUIT_REQUESTED the media_server ? It should do the trick
