I made this change and it will only work if I modify each of the thread
implementations to release the smart_ptr to runnable in the thread class after
the thread runs. I assume this is acceptable; once the runnable runs we don't
need the thread smart_ptr holding on to it any more; TServerFramework requires
the TConnectedClient (the runnable) to be destroyed when the client disconnects
to function properly.
