together v0.5.0 Together.Proxy
Proxy is here to receive all the Process.send_after
messages
It offloads the message handling from worker, and makes sure that if the worker dies, the respawned worker will still get the messages, since Proxy calls Worker by name instead of pid
If the Proxy dies, it will lose all the messages, but the Proxy is
less likely to die than Worker, because it has basically no logic
and no interaction with outside Together
