    No specific address is ever cited as a requirement for stack placement;
    stack immediately below text is merely given as a "typical arrangement".
    i.e. "Although applications may control their memory assignments, the
    typical arrangement appears below: [diagram and other bits]" It then
    goes on to say, "Processes, therefore, shount _not_ depend on finding
    their stack at a particular virtual address."

    The process address space boundary is, however, stated as a requirement:
    "the reserved area shall not consume more than 1GB of the address space."
