> Current RPC (really IPC) relies on client side timeouts to find "dead" 
> sockets. I propose that we have a thread that once a minute (if the 
> connection has been idle) writes a "ping" message to the socket. The client 
> can detect a dead socket by the resulting error on the write, so no client 
> side timeout is required. Also note that the ipc server does not need to 
> respond to the ping, just discard it.
