title: Google API client is really slow when building the drive v2 API
body: <p>The construction of the drive API service takes a very long time (10+ seconds).  I tried pickling the service and reloading it, but no joy.  Does anybody know how to get this thing to locally cache itself?</p>
  
  <pre><code>debug("Building Google Drive service")
  from apiclient.discovery import build
  self._service = build('drive', 'v2', http = http)
  
  debug("Initialisation complete")
  </code></pre>
