Looks good! You mentioned that 4GB of data are generated by requesting 256 bytes. It would be more interesting to see the throughput of 4 byte requests i.e. how many cprng_fast32() calls per second can we do? My vote would go to a cipher of Salsa20 family. They undergone quite more cryptoanalysis than HC-128. -- Mindaugas
