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
what
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
the
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
i
think.
