We need to extend plain random to support random-states. I plan to do it
once the random module in gnulib is usable.
Another option is to use Mersenne Twister PRNG, which I have in my local
tree (patch: http://paste.pocoo.org/show/ZYhLUPeXlkj405100KX4/). The
files mt19937.[ch] are from its authors'. Do you know if that can be
included in Emacs?
