and, btw, I stand by my assertion that statistical uniformity doesn't
matter for /dev/random. The uses the kernel has for random numbers
require unguessability, and /dev/random supplies this. If you need some
other property in user-space, it is *your* responsibility to verify that
/dev/random supplies this, not the kernel's. Repeatability, for example,
is often considered a virtue for simulation uses. The kernel doesn't
supply a *repeatable* random number stream, nor should it ever be required
to.
