Stop further event handlers on an element

I'm writing a little jQuery extension that prevents a user from double clicking on a link.

$.fn.preventDoubleClick = function() {
    return this.click(function() {
        var $t = $(this)
            , retVal = $t.data('active')  // check the internal flag
        ;
        if (retVal || retVal === undefined) { // if ON...
            $t.data('active', false);  // set the internal flag to OFF
            setTimeout(function() {
                $t.data('active', true);
            }, 1000);  // after 1 second, set the internal flag to ON
            console.log("allowed");
            return true;
        } else {  // if OFF...
            console.log("blocked");
            return false;
        }
    });
};

the problem is that if there are other click event handlers on the elements, they still fire:

$('#myLink').click(function() {
    console.log("Clicked");
});
$('#myLink').preventDoubleClick();

And now when you double click the link, I get this in my log:

allowed
clicked
blocked
clicked

So basically, I need the click function inside preventDoubleClick to stop all the other event handlers from firing. How can I do this?
