The fundamental issue with cron is that the current API does not allow robots to make "active" calls - all robot calls must be in response to an event. That means that the normal App Engine cron won't work, because the robot simply can't spawn off calls whenever App Engine calls it. That is why we added the special robot cron technique, but it is unfortunately fairly flaky. In the new API, active calls will be allowed and App Engine cron will be usable.
