    Hmm.. Some came to mind :

    Making /dev/random block if the amount requirements aren't met makes sense
    to me. If I request x bytes of random stuff, and get less, I probably
    reread /dev/random. If it's entropy pool is exhausted it makes sense to be
    to block.

    Just some mind spin.
