    The kernel users of random numbers may be unable to block.
    Thus the kernel has to have a PRNG anyway.
    You may as well export it.

    In theory. In practice what goes out through eg. the network is
    most important. Additional accesses to a PRNG bitstream unknown
    outside make it harder to predict the bitstream.
