Comment:

 I had to merge some other stuff to make the rand tests compile -- what do
 you think of my rust_rand_tests branch?  Before I merged it, I got errors
 like:
 {{{
    Compiling crypto v0.0.1

    |

    | ^^^^^^^^^^^^^^^^^^^^^

     |

     |             ^^^^^^^^^^^^^^^^^^^^^^^^^ no `ChaChaRng` in `rand`
