Redis / Node.js - 2 clients (1 pub/sub) causing issues with writes

Question

Trying to create two clients; one is pub/sub, the other is a standard connection. Is this not possible? There must be a way to abstract this to work :) Basically, if I do a get key after running test.js, all I see is 'valueBefore'. The output:

node test.js

The code:

var redis = require('redis');

var client1 = redis.createClient();
var client2 = redis.createClient();

client2.on('message', function (channel, message) {
    console.log('Received a message on channel: ' + channel);       

    client1.set('key', message, redis.print);

});

client2.subscribe('channel');

client1.set('key', 'valueBefore', redis.print);

setTimeout(
    function() {
        client2.publish('channel', 'valueAfter');
    },3000
);

You probably need to publish messages from client1 since client2 is dedicated to listening for messages on certain channel. Few words about this behavior are written in node_redis readme:

If you need to send regular commands to Redis while in pub/sub mode, just open another connection.
