(a) 32 bits is a bit less than five Eagles worth of byte-addressed data.  I
    can easily concoct a microprocessor application where direct addressing
    of that data space is desirable, if not necessary.  It won't be UNIX, of
    course.
(b) In any case, there are several address widths between 24 and 32.  What if
    I need 17 megabytes of virtual space?  I just saw a thing go by on
    unix-wizards that talked about running 60 MB processes - that takes 26
    bits.
