On the plus side, it gives a chance to write a pure C helper
function for creating many random numbers at a time.
On the minus side, random number generation is a much disputed
topic, occassionly requiring full disclosure of seeds and source.
Having the code in random.py makes it more visible than
burying it in the C code.
The C code I saw is covered by a BSD license -- I don't
know if that's an issue or not.
As for implementation difficulty or accuracy, the code is so short
and clear that there isn't a savings from re-using the C code.
