title: Can we do anything about a TransientError or does it indicate a server side issue?
body: <p>We see occasional (~100 per day) <code>TransientError</code> errors when adding tasks to a queue in appengine. Is there anything we can do to handle these or code more defensively to avoid them?</p>
  
  <p>An exampe of the error we receive is shown below: </p>
  
  <pre><code>  File "/python27_runtime/python27_lib/versions/1/google/appengine/ext/deferred/deferred.py", line 268, in defer
      return task.add(queue, transactional=transactional)
    File "/python27_runtime/python27_lib/versions/1/google/appengine/api/taskqueue/taskqueue.py", line 1132, in add
      return self.add_async(queue_name, transactional).get_result()
    File "/python27_runtime/python27_lib/versions/1/google/appengine/api/apiproxy_stub_map.py", line 604, in get_result
      return self.__get_result_hook(self)
    File "/python27_runtime/python27_lib/versions/1/google/appengine/api/taskqueue/taskqueue.py", line 1927, in ResultHook
      raise _TranslateError(e.application_error, e.error_detail)
  TransientError
