Have you tried screen? If you use the '-d -m' options then it should
launch the screen session in the background. If you start it with a
specific command then it'll exit when it's finished running. So you'll
want something like: 'system("screen -d -m lame $lame_options")'. Also
might be useful to add a name to the screen with the -S option
(something like the users login name?) so you can easily see what's
doing what when you look at the screen list (screen -ls).
