> I just tried running the tests on a default build on Ubuntu 20.04 with an AMD
> Ryzen CPU (where presumably RDRAND can't be relied on, but I don't know if
> that's the underlying reason), and the tests appear to hand blocking on
> {{std::random_device}} at some point. I suppose some versions of libstdc++
> will use {{/dev/random}} instead of {{/dev/urandom}} (which is a bad idea in
> itself).
> We should probably try to minimize our usage of {{std::random_device}}. After
> all, we're not generating cryptographic keys or anything.
