So um, that means using it to produce a UUID is ok as long as I'm willing to
accept the odds
of a clash (very unlikely).
I've more chance of being hit by a bus than having to deal with the
consequences of a little ID clash in my system. Therefore I should focus my
energies on watching out for buses than coding around clashes of IDs.
Maybe I should go to bed !
