Will Google throttle attempts to obtain user location using client-side jsapi calls?

Question

I installed this JavaScript project which attempts to obtain the user's geolocation using client-side JavaScript.

https://github.com/codejoust/session.js/

The default mechanism for the location lookup is Google's jsapi feature.

Will Google throttle my app's ability to obtain this information after a certain number of requests?

The function in question looks like this:

gapi_location: function(){
      return function(callback){
        var location = util.get_obj(options.location_cookie);
        if (!location || location.source !== 'google'){
          win.gloader_ready = function() {
            if ("google" in win){
              if (win.google.loader.ClientLocation){
                win.google.loader.ClientLocation.source = "google";
                callback(win.google.loader.ClientLocation);
              } else {
                callback({error: true, source: "google"});
              }
              util.set_cookie(
                options.location_cookie,
                util.package_obj(win.google.loader.ClientLocation),
                options.location_cookie_timeout * 60 * 60 * 1000);
            }}
          util.embed_script("https://www.google.com/jsapi?callback=gloader_ready");
        } else {
          callback(location);
        }}
    },
