Method predictSerializedSize

src/DeleteRequest.java:516–538

Predicts a lower bound on the serialized size of this RPC. This is to avoid using a dynamic buffer, to avoid re-sizing the buffer. Since we use a static buffer, if the prediction is wrong and turns out to be less than what we need, there will be an exception which will prevent the RPC from being ser

   * prevent the RPC from being serialized.  That'd be a severe bug.
