* A buffered GRXWriter.
*
* GRPC only allows a single message to be written to a channel at a time. While the channel is
* sending, GRPC sets the state of the GRXWriter representing the request stream to
* GRXWriterStatePaused. Once the channel is ready to accept more messages GRPC sets the state of
* the writer to GRXWriterStateStarted.
*
* This class is NOT thread safe, even though it is accessed from multiple threads. To conform with
* the contract GRPC uses, all method calls on the FSTBufferedWriter must be @synchronized on the
* receiver.
