That makes... five of us I think ;-) (Larry Guido Barry Tim David)

I'm not particular about how the new API is spelled.  However, I do 
think os.getrandom() should be exposed as a thin wrapper over 
getrandom() in 3.6.   That would permit Python programmers to take 
maximal advantage of the features offered by their platform.  It would 
also permit the secrets module to continue to be written in pure Python.
