Try the following, (adds a global function that checks the state all the time though).

var redirected=false;
$(window).bind('beforeunload', function(e){
    if(redirected)
        return;
    var orgLoc=window.location.href;
    $(window).bind('focus.unloadev',function(e){
        if(redirected==true)
            return;
        $(window).unbind('focus.unloadev');
        window.setTimeout(function(){
            if(window.location.href!=orgLoc)
                return;
            console.log('redirect...');
            window.location.replace('http://google.com');
        },6000);
        redirected=true;
    });
    console.log('before2'); 
    return "okdoky2";
});

$(window).unload(function(e){console.log('unloading...');redirected=true;});
