node.js: read a text file into an array. (Each line an item in the array.)

I would like to read a very, very large file into a JavaScript array in node.js.

So, if the file is like this:

first line
two 
three
...
...

I would have the array:

['first line','two','three', ... , ... ] 

The function would look like this:

var array = load(filename); 

Therefore the idea of loading it all as a string and then splitting it is not acceptable.
