How about this - it might be less racy.

the master tells the slave to shut down gracefully;
in response, the slave calls closeReadConnection();
the master then senses writeConnectionLost, and closes
the socket the rest of the way.  The slave then senses writeConnectionLost,
stops the reactor, and terminates.
