implied stability between minor versions.
2. Fix i

If I'm given a random int, x, in the range [0, 12), and asked to produce from
it a random int, y, in the range (0,8], I&#

stop-start range approaches 2^53 the output becomes noticeably biased. This bug
also affects random.SystemRandom.
For example, counting the number of even ints in a set of 10^6 random
