> List append relies on TimeUUID.Generator.nextUnixMicro, which relies on the
> local clock’s millisecond clock. In jvm-dtest all instances share the same
> physical clock, so most of the time time moves forward uniformly, but there
> is an edge case when the test “runs too fast” and creates a new TimeUUID
> within the same millisecond, when this happens a logically later timeuuid can
> happens-before a logically earlier timeuuid!
