Considering Knuth's stamp of approval, and the purpose of Jeremy's original
intent for his random() inclusion, Chris provides a good argument.  A
portable pseudo-random number generator that makes up for poor random that
comes natively with some distributions (ones that only alternate the higher
order bits).

It's hard to argue against a PRNG that has a period of 2^19937-1 with
tight, fast code generation.
