Reads don't trigger reseeds in Yarrow. And both Yarrow and Fortuna are
designed so this isn't a problem. In any case reads that aren't under
the control of an unprivileged attacker make it harder to perform a
state-extension attack, not easier.
This kind of thing shouldn't be an issue for any non-blocking random
device that isn't quite badly broken. If it were, it would be better to
fix the device.
