> When a stripping cell is full, writeChunk computes and generates parity 
> packets.  It sequentially calls waitAndQueuePacket so that user client cannot 
> continue to write data until it finishes.
> We should allow user client to continue writing instead but not blocking it 
> when writing parity.
