The above code uses `ctPicosec` as seed. Is it better to
Admittedly, I don't know much about this from the haskell end or about the
particular api.
If you want statistical randomness, your seed doesn't matter; just the PRNG.
I might even have seeded with a constant or taken the seed from the user.
Seeding from urandom will make your output more
It probably is, but definitly not portable. Try to find /dev/urandom
under Windows.
