Sounds good to me except that I'd like to have the option to get
poor randoms. getrandom() is used when /dev/urandom is not accessible
or painful to use. Until we provide applications with a solution to
this fairly common need, the problem will continue to regularly pop
up, in a different way ("my application randomly crashes at boot").
Let's get GRND_INSECURE in addition to your change and I think all
needs will be properly covered.

Thanks,
Willy
