`random' is supposed to be a PRNG, not an RNG.
I don't see any reason why we should make it significantly better than
libc's own PRNG (i.e. any bug report on a weakness of our `random'
should be forwarded to the corresponding libc's maintainers).
OTOH we should provide a way to seed the PRNG with an RN as well as to
re-seed it with the same seed.
