> Currently we don't have the {{relink}} functionality in libprocess.  i.e. A way to create a new persistent connection between actors, even if a connection already exists. 
> This can benefit us in a couple of ways:
> - The application may have more information on the state of a connection than libprocess does, as libprocess only checks if the connection is alive or not.  For example, a linkee may accept a connection, then fork, pass the connection to a child, and subsequently exit.  As the connection is still active, libprocess may not detect the exit.
> - Sometimes, the {{ExitedEvent}} might be delayed or might be dropped due to the remote instance being unavailable (e.g., partition, network intermediaries not sending RST's etc).
