process: Clean up connection retry logic
Its possible for a connection to connect to the server as its shutting down
but before its removed the socket file. This patch:
a) Removes the socket file earlier to avoid connections.
b) Handles EOFError in initial connections gracefully. These occur if the
socket is closed during the server shutdown.
c) Ensure duplicate events aren't shown on the console. This makes debugging
these issues very very confusing.
With these changes the backtrace that was concerning users is hidden and the
server works as expected with a reconnect when it catches it in a bad state.
