* Mersenne Twister PRNGs are NOT cryptographically safe either, although
  the random number generation period is much much longer (approx. 2^43
  on AS183, (2^19937) - 1 for SFMT) and the state space is far less
  easier to be exploited.

* sfmt-erlang is now runable on non-NIF environment (though it's slow)

* I've been working on a lightweight variant of MT called TinyMT (period:
  (2^127) - 1, internal state: 28 bytes), including compatibility
  functions to the random module, and is capable of generating ~2^58
  different RNG streams.  It's at
