You do realize that the age of the universe is only on the order of
around 10^18 seconds, do you? Even if you had a trillion CPUs each
chugging along at 3.0 GHz for all this time, the number of processor
cycles you will have executed cumulatively is only on the order 10^40,
still 37 orders of magnitude lower than the chance for a random hash
