Neither of these will necessarily work. Instead, you want to use a
shutdown hook:
reactor.addSystemEventTrigger("before", "shutdown", f)
when you do reactor.stop(), f will be called... and shutdown will be
delayed until the Deferred f returns is triggered. In your case, send
message, tell connection to close, and then stop reactor. If you make
sure the Deferred from f only gets callback()ed when connectionLost is
called you'll get behavior you want.
