True. However if you generate lots of 64-bit values and see a
collision between any two, that is much more likely. See "birthday paradox".

I know you understand this, David. Just so everyone else is clear,
because part of this thread is about locking problems (same result
within a short time), and part of this thread is about uniqueness
(collisions between any pair).

Enjoy,
