bq. That's because we took opposite approaches. Your PR's approach is "if this 
connection says the sender address is a listening socket, then also consider 
that address when sending events about the remote process".

bq. My PR takes the opposite approach: the address of the remote process is 
always the address of the socket used to connect, regardless of whether its 
also listening in another socket.

bq. I think my approach is in the end more correct, but requires more code to 
fix existing code. In my view, RpcCallContext.senderAddress should be the 
address of the socket that sent the message, not the address the remote process 
is listening on.
