Make UUID generation failable
Previously, this would always succeed, but might use
weak random numbers in rare failure cases. I don't think
these UUIDs are security-sensitive, but if they're generated
by a PRNG as weak as rand() (<= 32 bits of entropy), we
certainly can't claim that they're universally unique.
