case class LastWriterWins[+A](timestamp: CausalTime, payload: A)

A LastWriterWins (register) is a common fallback for datatypes that don’t have good merge semantics.

Concurrent writes are resolved by a causality preserving clock based on milliseconds, using a random value as a tie breaker. The random values are non-fair, so a specific replica is more likely to win.
