title: thread warnings in Phonegap/Cordova app
body: <p>I am getting these two <em>thread warnings</em> compiling on an iPhone (iOS 6):</p>
  
  <pre><code>THREAD WARNING: ['InAppBrowser'] took '260.519043' ms. Plugin should use a background thread.
  THREAD WARNING: ['Geolocation'] took '110.953857' ms. Plugin should use a background thread.
  </code></pre>
  
  <p>this is how I call the plugins in my code:</p>
  
  <pre><code>window.open("http://www.anaddress.com", '_system');
  </code></pre>
  
  <p>and this is how my config.xml looks like:</p>
  
  <pre><code>&lt;?xml version='1.0' encoding='utf-8'?&gt;
  &lt;widget id="my.id" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0"&gt;
      &lt;name&gt;Hello Cordova&lt;/name&gt;
      &lt;description&gt;
          A sample Apache Cordova application that responds to the deviceready event.
      &lt;/description&gt;
      &lt;access origin="*" /&gt;
      &lt;preference name="AllowInlineMediaPlayback" value="false" /&gt;
      &lt;preference name="AutoHideSplashScreen" value="true" /&gt;

      &lt;preference name="FadeSplashScreenDuration" value=".25" /&gt;
      &lt;preference name="HideKeyboardFormAccessoryBar" value="false" /&gt;
      &lt;preference name="KeyboardDisplayRequiresUserAction" value="true" /&gt;
      &lt;preference name="KeyboardShrinksView" value="false" /&gt;

      &lt;preference name="ShowSplashScreenSpinner" value="true" /&gt;

      &lt;feature name="Notification"&gt;
          &lt;param name="ios-package" value="CDVNotification" /&gt;
      &lt;/feature&gt;
      &lt;feature name="Geolocation"&gt;
          &lt;param name="ios-package" value="CDVLocation" /&gt;
      &lt;/feature&gt;
      &lt;feature name="InAppBrowser"&gt;
          &lt;param name="ios-package" value="CDVInAppBrowser" /&gt;
      &lt;/feature&gt;
      &lt;author email="mail@exam.de" href="http://www.example.com"&gt;Me
      &lt;/author&gt;

      &lt;preference name="fullscreen" value="true" /&gt;
      &lt;preference name="webviewbounce" value="true" /&gt;
  &lt;/widget&gt;
  </code></pre>
  
  <p>Of course I installed the plugins using the cordova CLI:</p>
  
  <pre><code>$ cordova plugin add org.apache.cordova.inappbrowser
  </code></pre>
  
  <p>Any help would be appreciated, Thanks!</p>
