Bah. Got that backwards and calculated wrong. The probability of no
collisions is
exp(-(2**60) / (2*2**160)) = exp(-(2**-101)) = approx (1 - 2**-101)
which is very close to 1. The probability of collision is about
2**-101 which is close to 0. Proofread first, then post. I keep
getting that in the wrong order.
