Personally I think it would have been better to name the yarrow device
as /dev/urandom and create a new device, say  /dev/entropy , which would
function as a traditional /dev/random. One would then have the choice
of linking /dev/random to either /dev/entropy or /dev/urandom. And in
the second case /dev/entropy would still be availible in special cases. 

Essentially what has happened is that /dev/random has been abandoned in
favour of a better /dev/urandom, and that seems to be a bit high-handed
to me.
