If your expecting keyup to fire before the key is released, that is not how key events work. When you hold a key down for more than about half second key down events are fired repeatedly until you release the key. Only after the key is released the keyup event should be fired.

You don't have to take my work for it though, If you look at KeyboardJS's source code its just piping native DOM events. At no point does the library create events from scratch.

If you want a keypress event you can ether wait till I'm done KeyboardJS 1.0.0 or you can bind to keydown and ignore any following events.
This is an example of a function that can accomplish this.

KeyboardJS.bind.keypress = function(keyCode, callback) {
    var keyPressed = false;

    return KeyboardJS.bind.key(keyCode, function() {
        if(!keyPressed) {
            keyPressed = true;
            if(typeof callback === 'function') { callback(); }
        }
    }, function(){
        keyPressed = false;
    });
}

By the way, JavaScript doesn't randomly break because of "crap you have a javascript do in the background", unless you are overwriting global variables. The language should always be predictable (that is if you undertand functional programming with lambda patterns). Also note that JavaScript and the DOM interface are separate and most bugs can be attributed to the DOM.
