KCL not doing what I'm expecting it to do

I'm running the sample code.

I'm running

``` bash
sample_kinesis_wordputter.py --stream words -w cat -w dog -w bird -w lobster
```

and I get some words pushed

``` log
Connecting to stream: words in us-east-1
Put word: cat into stream: words
Put word: dog into stream: words
Put word: bird into stream: words
Put word: lobster into stream: words
```

but when I run python sample_kclpy_app.py, I don't have any output.

I'm expecting python sample_kclpy_app.py to ouput "getting word: cat..." or something along those lines.

Am I missing something? It looks like the stream is not being listened to.
