We had this a while ago, and Don was kind enough to post some bindings
to dSFMT:
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mersenne-random-pure64-0.2.0.2

which could have a purer interface, but then the upstream code could be
less blatantly impure. 

Anyway, that's about as fast as you can get.
