 // BufferedSocketWriter and BufferedDatagramWriter implement write data queue
 // for stream and datagram sockets. BufferedSocketWriterBase is a base class
 // that implements base functionality common for streams and datagrams.
 // These classes are particularly useful when data comes from a thread
 // that doesn't own the socket, as Write() can be called from any thread.
 // Whenever new data is written it is just put in the queue, and then written
 // on the thread that owns the socket. GetBufferChunks() and GetBufferSize()
 // can be used to throttle writes.
