Ok, I think we could do a better job of explaining the semantics. The system does not implement idempotency by default. If something that's not marked as "idempotent" fails, it does try again in a different machine. If the function is marked as idempotent [1] then the system ensure at-most-once semantics by only issuing the call once and only once to a worker who can process the call.
