Over_Query_Limit in Google Maps API V3: How to Pause/Delay in JavaScript to Slow It Down

OVER_QUERY_LIMIT in Google Maps API v3: How do I pause/delay in Javascript to slow it down?

Nothing like these two lines appears in Mike Williams' tutorial:

    wait = true;
    setTimeout("wait = true", 2000);

Here's a Version 3 port:

The relevant bit of code is

  // ====== Geocoding ======
  function getAddress(search, next) {
    geo.geocode({address:search}, function (results,status)
      { 
        // If that was successful
        if (status == google.maps.GeocoderStatus.OK) {
          // Lets assume that the first marker is the one we want
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          // Output the data
            var msg = 'address="' + search + '" lat=' +lat+ ' lng=' +lng+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          // Create a marker
          createMarker(search,lat,lng);
        }
        // ====== Decode the error status ======
        else {
          // === if we were sending the requests to fast, try this one again and increase the delay
          if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
            var reason="Code "+status;
            var msg = 'address="' + search + '" error=' +reason+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          }   
        }
        next();
      }
    );
  }

Google Maps API OVER_QUERY_LIMIT

It seems like you may be going over the "# or requests per second" limit. As mentioned in the documentation:

You can exceed the Google Maps API Web Services usage limits by:

• Sending too many requests per day.
• requests too fast, i.e. too many requests per second.
• requests too fast for too long or otherwise abusing the web service.
• Exceeding other usage limits, e.g. points per request in the Elevation API.

To verify that you are hitting that limit:

Upon receiving a response with status code OVER_QUERY_LIMIT, your
application should determine which usage limit has been exceeded. This
can be done by pausing for 2 seconds and resending the same request.
If status code is still OVER_QUERY_LIMIT, your application is sending
too many requests per day. Otherwise, your application is sending too
many requests per second.
