(Get the code!)
The birthday paradox numbers aren't very scary; at a trillion objects, the chances of a single collision are still like 10^-18. Of course that's assuming MD5 is perfectly distributed, which we know it isn't.
In some future perfect world, we should probably just let people choose other algorithms like sha256, just so this stops being an issue for discussion. I'll really miss how fast md5 is, though.
