Google Maps API V3 throttle queries

I have been trying to throttle google maps api query over so that it will return more than 10 queries all morning with no luck. I have used this code here http://pastebin.com/X0icm1B8. I tried wrapping .each in a setTimeOut function at line 44 as well as trying it with the marker var but not luck. I found several results in google but haven't been able to get any of them to work in my code. Any help would be great thanks so much in advance.

You need to grab all the addresses and sending them over in an array in one shot instead of one by one.

Here is how I figured it out. With help from this post http://stackoverflow.com/questions/9796730/setinterval-or-settimeout-for-google-map-v3?codekitCB=410851502.832954 I created a new array for the addresses with a function. Then place the existing address query inside a function with some changes. This allowed me to instead of setTimeout use setInterval. Worked perfect. Below is the code if anyone else needs it.

var map,
bounds,
geocoder,
addresses = new Array(),
center;

function addMarkerToMap(location, address){
//var image = "assets/img/set_image.png"; // Replace set_image.png with image path 
var marker = new google.maps.Marker({
map: map,
position: location,
//icon: image
});

bounds.extend(location);
map.fitBounds(bounds);

var infoWindow = new google.maps.InfoWindow({
content: address
});

google.maps.event.addListener(marker, 'click', function() {
infoWindow.open(map, marker);
});
}

function initialize() {
var mapOptions = {
scrollwheel: false,
mapTypeControl: false,
streetViewControl: false,
zoom: 10,
center: new google.maps.LatLng(37.09024, -95.712891),
mapTypeId: google.maps.MapTypeId.ROADMAP
};

map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
geocoder = new google.maps.Geocoder();
bounds = new google.maps.LatLngBounds();
}

initialize();

// Created the array 
function getAddresses () {
$('address',parent.window.document).each(function () {
addresses.push($(this).html());
});
}

getAddresses();
theInterval = setInterval('codeAddress()', 100); // Set the Interval

// New Function for address
function codeAddress() { 
if (addresses.length == 0) {
clearInterval(theInterval);
}

var address = addresses.pop();

geocoder.geocode({ address: address }, function( results, status ) {
if(status == google.maps.GeocoderStatus.OK) addMarkerToMap(
results[0].geometry.location, address );
});
}

google.maps.event.addDomListener(map, 'idle', function() {
center = map.getCenter();
});

$(window).resize(function() {
map.setCenter(center);
});
