I'd love to contribute to this discussion, but I don't know what these
different names mean.  I think what we need to talk about is all of
the different memory parameters we need, and then what each of the
individual names mean -- what they currently map to, and then what we
want them to map to.  At very least they should be in a comment
somewhere.
