I think relying on a combination of futex and ram latency benchmarks
would be enough to provide a reliable source of entropy.

At least a reliable source of entropy of at least 64-bits, of which
there are cheaper ways to break ciphers than through brute force.

Unfortunately, the data turns out to be very noisy. It's very hard to
see if there is a noticeable delay related to the refresh cycles.
