-// A StreamSocket decorator. All functions are passed through to the wrapped
-// socket, except for Write().
-//
-// Writes are buffered locally so that multiple Write()s to this class are
-// issued as only one Write() to the wrapped socket. This is useful to force
-// multiple requests to be issued in a single packet, as is needed to trigger
-// edge cases in HTTP pipelining.
-//
-// Note that the Write() always returns synchronously. It will either buffer the
-// entire input or return the most recently reported error.
-//
-// There are no bounds on the local buffer size. Use carefully.
