Moreover, SplitMix has a published paper to describe it, which is massively better (in a tricky area) than an un-documented pile of code. I knew that Guy was working on this but I didn't know it was now published.  Excellent!

I would love to see this happen

|  With regards to random, rather than making System.Random
|  crypographically sound (which, as I understand it, could require
|  changes to the API), there is a “halfway house” approach —
|  implementation of the SplitMix algorithm of Steele, Lea and Flood [1].
