> There is a race condition involving the ByteByffer incomingBuffer, a field of 
> ClientCnxn.SendThread. SendThread reads a packet in two steps: first it reads 
> the length of the packet, followed by a read of the packet itself. Each of 
> these steps corresponds to a call to doIO() from the main loop of run(). If 
> there is an exception or the session times out, then it may leave 
> incomingBuffer in an inconsistent state. 
> The attached patch adds code to reset incomingBuffer upon a call to 
> SendThread.cleanup(). This method is called upon an exception on run().
