The main reason I went for this approach was because I felt that placing it behind one knob would raise the question: "What's so special about these two? Why is stderr treated separately? Why not disable stdin and stderr, or stdout and stderr?" The patch demonstrates that apart from the tying, stdin, stdout and stderr are separate.

That said, I wouldn't mind merging this, as long as we can get a nice compromise between getting the code to work on CloudABI while keeping it readable. Thoughts?
