edu.brown.hstore.callbacks.RemotePrepareCallback
This is callback is used on the remote side of a TransactionPrepareRequest so that the network-outbound callback is not invoked until all of the partitions at this HStoreSite are finished preparing the transaction. @author pavlo

        RemoteTransaction ts = this.hstore_site.getTransaction(txn_id);
        assert(ts != null) : "Unexpected null transaction handle for txn #" + txn_id;
        
        // Always create a new prepare callback because we may get multiple messages
        // to prepare this txn for commit. 
        RemotePrepareCallback wrapper = ts.getPrepareCallback();
        assert(wrapper.isInitialized() == false);
        wrapper.init(ts, partitions, callback);
        
        this.hstore_site.transactionPrepare(ts, partitions, wrapper);
    }
