79 *
80 * The socket support in pegasus is schizophrenic. Some code uses
81 * an Sint32 (fd) as a socket, while other code uses a pointer to an
82 * MP_Socket, which is kind of a container for either an Sint32 socket
83 * or an SSL socket.
84 *
85 * Then there is also the local socket. (AF_UNIX).
86 *
87 * What we need to make all of this coherent is a general-purpose
88 * socket class that uses polymorphism to provide a good sockets
89 * interface.
90 * Because of what we are planning for the pep_88 connection management
91 * code this general-purpose socket class should be reference counted.
