But its not clear to me how to ensure uniqueness when its based on
randomness from the generators.

Even with a perfect random generator non-unique values are possible (that's why it's random). It's unlikely, but it can happen. The question is whether the probability of non-unique values from /dev/urandom is any higher than that for values read from /dev/random. One _might_ be able to predict the values from /dev/urandom.
