> Right now, with pessimistic locking:
> TransactionManager.begin()
> Object k = cache.put(k,v); //this performs two RPCs to same nodes: a ClusterGetCommand and an LockControlCommand.
> The two RPCs can be merged together.
> Whilst this is an optimisation, it is quite an important one as it has an major impact on performance on every put.
