According to
http://www.pcg-random.org/other-rngs.html

This chacha20 implementation is seedable and should be reproducible:

...though I am concerned about the k-dimensional equidistribution as a 
scientist, and also that if the random number generator is changed without 
the interface changing, then it may screw up tests and existing codes which 
rely on a particular sequence of random numbers.
