Shouldn't you end with & disown to fully detach?

IIRC disown is a shell built-in command, so its use is a bit limited. Not sure if & is also a built-in, but I found disown to not work in some situations. Besides, it's shorter.

shell built-in command

After looking into it a bit more, its at least a builtin for bash but is otherwise not POSIX. I guess nohup ... & would be the POSIX compliant equivalent, though still not a builtin.

Its my understanding that & backgrounds, not necessarily detaches, a process -- if the parent process closes, I think the background tasks would still be wait()ed on, if only using &.
