/***
 * This class wraps an input stream, storing a reference to its originating
 * socket.  When the stream is closed, it will also close the socket
 * immediately afterward.  This class is useful for situations where you
 * are dealing with a stream originating from a socket, but do not have
 * a reference to the socket, and want to make sure it closes when the
 * stream closes.
