TestPolicyExecute often times out on rpc to __engine

[Eric K]

Example:
Traceback (most recent call last):
  File "congress/tests/test_congress.py", line 269, in test_policy_execute
    self.api['api-policy'].add_item({'name': 'alice'}, {})
  File "congress/api/policy_model.py", line 105, in add_item
    raise webservice.DataModelException.create(e)
congress.api.webservice.DataModelException: Not Found::Request to service '__engine' timed out
