I agree, I see almost no reason to prefer /dev/random over /dev/urandom. The only cases that I can think of are

i) 128-bits isn't enough entropy (it is, honest)
ii) The machine has just booted (perhaps even for the first time), so that the entropy pool doesn't have enough entropy in it. This might be reasonable say for RedHat's generating an ssh key the first time sshd is started.
