A couple of points:
(1) In addition to documenting the extent of the repeatability, it would be
good to have tests to prevent changes that inadvertently change the sequence of
randrange values.
(2) For large arguments, cross-platform reproducibility is already a bit
fragile. For example, the _randbelow function depends on the system _log
function---see the line
k = int(1.00001 + _log(n-1, 2.0))
Now that we have the bit_length method available, it might be better to use
that.
