Since you're doing nothing with STDERR, it would go to the tty.

It is the case that if you are writing to STDERR and STDOUT and you only pipe one of them, then you'll find that the other will need to go to the tty. Only if you pipe both of them you'll find that the tty is not required. > I guess I could use a pre written module, but I would > prefer to do it my self as I would like to understand > linux at a more low level. I think you're looking too deep. The fact is the program wants to print something and it's got nowhere to go.
