A process cannot open multiple redis instances?

Hi, I want to create two queue in my process.But only the first queue created is useful.0

``` js
var kue = require('kue');
var queue2 = kue.createQueue({
redis: {
post: 6379,
host: "127.0.0.1",
db: 2,
}
});
var queue3 = kue.createQueue({
redis: {
post: 6379,
host: "127.0.0.1",
db: 3,
}
});
// create job
queue2.create('test2', {x: 2}).save()
queue3.create('test3', {x: 3}).save()
```

when I check the queue, the `queue2` has two job. `queue3` has none job;
How can I create multiple queue in one process? Thanks.

Start by running the supplied two-queue script and inspect the kue.createQueue Redis options path, comparing the connection details for db 2 and db 3. Done means jobs created through queue2 and queue3 are stored and visible in their respective Redis databases.
