- Streams don't in and of themselves provide a "clean" way of writing
- user-level window managers. As Henry pointed out, a pseudo-tty is what you
- want here; you have a window manager that simulates a terminal (using a real
- terminal or some other sort of display) and provides a tty-like interface to
- clients using a pseudo-tty.
-
- Streams might permit a fairly clean implementation of a pseudo-tty, but they
- don't provide the only clean way of writing user-level window managers; any
- sufficiently powerful pseudo-tty mechanism will do that. Streams might
- provide the cleanest way of providing a sufficiently powerful pseudo-tty
- mechanism.
