Hi there,
I am just discovering node-java, and I like it a lot. Thanks for this library.
I was unable to find any mention of this problem:
When using the Hello World example, it seems that node-java does not finish by itself, and I need to actively interrupt the call.
example my node file "testHelloWorkJSCallingJava.js":
```
var java = require('java');
var javaLangSystem = java.import('java.lang.System');
javaLangSystem.out.printlnSync('Hello World!');
````
When I execute it using node it wxorks fine, but it does not quit, and I have to press Ctrl+C to stop:
```
simpleJSToJava % node testHelloWorkJSCallingJava.js
Hello World!
```
Is there anything I am missing?
