This morning, I finished off and packaged up a library (CL, linux; other OSes with CL implementations and OS-provided random (or random-backed pseudorandom) devices can probably be grafted in, but would require volunteers to test) to extract random bits from /dev/urandom and use those essentially unadorned to generate random numbers.
There's a single exported function from the package, RANDOMNESS:RND and takes an integer argument (I guess you could try feeding it a float, but it wouldn't do you that much good). That function then proceeds to extract log2 N bits and uses rejection smapling to find an integer in the 0..(N-1) span. As the bits sucked out of the internal pool run out (each bit is used only the once), they're replenished from the OS-provided randomness source.
All very nice, with some interesting corner cases for the unwary and probably still bug-ridden. But, such is life.
