I've looked if we couldn't we work around this by declaring another static variable with __latent_entropy and use it to initialize net_rand_state early, for example in prandom_init(), but there we already fill net_rand_state with randoms so I'm wondering if that __latent_entropy is used before prandom_init() or if its sole purpose is to provide extra initial entropy to be combined with the one prandom_init() will add.
