Subject Re: Order of tuples

Between two tasks the ordering is maintained. So if the spout and the bolts have a parallelism
of one the ordering will be usually maintained. However currently there are some cases where
messages are dropped at the source worker if the connection to the destination worker goes
down and the messages gets replayed. In this case ordering cannot be guaranteed.
