Alternatively, we could take the unwhitened output and just feed it into /dev/random (since the /dev/[u]random entropy pools will take care of doing the whitening for us).
This is exactly what the Entropy Key's daemon does. There's no point in engaging in whitening and the like, since the key already does all of that (mixing together the output of two RNGs, making sure they are not correlated, and the like) and the daemon just asks the key 'are you broken?' and stops feeding entropy into /dev/random if it says it is.
