Hmmm. At that rate, we'll use up the extra 32 bits in our
64 bit pointers in another 48 years. So 128-bit machines
ought to be making an appearance around about 2057, and
then we'll be all set until 2153 -- if we're still using
anything as quaintly old-fashioned as binary memory
addresses by then...
