-------------------------------------------

CASSANDRA-2034 does improve this a bit, since we know a hint was stored for the timed out replica(s).

> Contrarily to standard insert, counter increments are not idempotent. As such, replaying a counter mutation when a TimeoutException occurs could lead to an over-count. This alone limits the use cases for which counters are a viable solution, so we should try to come up with a mechanism that allow the replay of a failed counter mutation without the risk of over-count.
