I want to prevent double form submissions within a small window, then allow the form to be submitted again.

I wrote this script after looking at several examples, but the global variable is bugging me. I'd welcome any suggestions on improving it.

var aLockedForms=   [];
jQuery.fn.preventDoubleSubmit=  function() {

    jQuery( this ).submit( function() {
        if ( this.beenSubmitted )
            return false;

        this.beenSubmitted= true;

        aLockedForms.push( this );

        setTimeout( function() {
                        var domTarget=  aLockedForms.shift();
                            domTarget.beenSubmitted=    false;

                    } ,
                    1984 );

    });

};

                    } ,
                    1984 );

    });

};

After the DOM is loaded, I run the following:

$( "form" ).preventDoubleSubmit();
