It would not always result in a successful exploitation; just as flipping
the coin twice is not a guarantee of getting tails once.
Other than that, the amount of randomization is indeed puny; but then,
even 32-bit randomization is a good defense only in certain situations,
and often, can be defeated with some time, aided by luck or a decent
NOP-equivalent sled.
