Even given that, we noticed a distinct pattern in random when we were using
it, and ended up calling it 6 or 7 times just to kick start it into some
degree of unpredictability. If you actually need a proper random number
generator (for encryption etc, where it could matter) you might check out
the Boost libraries - they have some good stuff.
