    T streams are made up from (or are higher level abstractions of) T
    channels.  Channels are implemented in a machine-dependent way,
    whereas streams are machine-independent.

In the interest of accuracy I'd like to say that this is only true of
streams returned by OPEN or MAYBE-OPEN.  Other kinds of streams don't
necessarily deal with files or "channels" at all.
