That's the answer to your question, right?

I don't think somebody ever did a thorough review though.

Concerning the rng wrappers, currently this is a C-code 5 minute
implementation which should be _completely_ rewritten (this used to be
in my BFL "roadmap document" :-). C++-ify the code (making it
threadsafe along the way) and providing support for changing the seed
are 2 things that jump to my mind.
