I think you're being unduely pessimistic (or do you know something I
don't?).  You seem to be assuming that the CMTS will allocate upstream
minislots on a first-come first-served basis, but if I were writing the
code, I'd certainly use a priority-based scheme where small requests
take precedence over large requests.  I'd probably also keep some rough
usage statistics (one counter per CM) so that I could give precedence to
low bandwidth users.  With that kind of a system, heavy upstream usage
by Y and Z would affect only them, not A-X.
