Currently, restarting the forwarder will send again all OS messages the HMC has buffered.

This needs to be improved such that the forwarder is aware of the last message sent for each partition. Since this data needs to survive a forwarder restart, it needs to be persisted in the file system.

Python's built-in "shelf" could be used to persist the message numbers upon exit.
