This busted StressTest and StressTestNonBlocking because they are coded to
assume that the thread shared pointer will hold on to the runnable after the
thread is gone. The TConnectedClientTracker is therefore necessary to avoid
breaking existing clients that might depend on this behavior of Thread, so I am
not going to simplify to a map of TConnectedClient* to shared_ptr<Thread>.
