Detecting load failures with head.js

When a required script doesn't load, the callback fires even if the script load fails (404):

function callback () {
    console.log('callback,', arguments);
}

head.test({
    test: 1 === 1,
    success: ["/non-existant.js"], 
    failure: [],
    callback: callback
});

In the above example, the console outputs this regardless of whether or not the script file is loaded:

callback, []

Is there a way to handle that?
