-
-//
-// TODO: This class is useful but adds a lot of
-// overhead. There are many improvements we can
-// make here:
-//
-// - There should be a generic Buffer class, ac-
-//   comodating a list of memory buffers. This
-//   would enable the use of the readv() and
-//   writev() functions to perform the I/O on
-//   the socket.
-//
-// - The buffering should be moved to the Write-
-//   Buffer and ReadBuffer classes. By performing
-//   the buffering here and there, we are dupli-
-//   cating a lot of code and are adding a lot
-//   of useless memory copies.
-//
-// - Stream compression should be removed. The
-//   proxy should compress the frames based on
-//   the type and should include the length of
-//   the decompressed data in the header of the
-//   packet. Besides avoiding the compression
-//   of packets that cannot be reduced in size,
-//   we would also save the additional memory
-//   allocations due to the fact that we don't
-//   know the size of the decode buffer at the
-//   time we read the packet from the network.
-//
-// - The other utilities implemented here, like
-//   the functions forcing a write on the socket
-//   or waiting for more data to become available
-//   should be moved to the Proxy or the Channel
-//   classes.
