I read the readme but I didn't find any info about delivery guarantees. Do we know if tasks are guaranteed to be delivered once and only once, or if there is possible data loss or duplication?

It's worth noting that exactly-once delivery is impossible: http://bravenewgeek.com/you-cannot-have-exactly-once-deliver...

By specifying a timeout on a task spec or not you can specify whether a task is tried at least once or at most once.
