67 *
68 * The socket support in pegasus is schizophrenic. Some code uses
69 * an Sint32 (fd) as a socket, while other code uses a pointer to an
70 * MP_Socket, which is kind of a container for either an Sint32 socket
71 * or an SSL socket.
72 *
73 * Then there is also the local socket. (AF_UNIX).
74 *
75 * What we need to make all of this coherent is a general-purpose
76 * socket class that uses polymorphism to provide a good sockets
77 * interface.
78 * Because of what we are planning for the pep_88 connection management
79 mday 1.1.2.1 * code this general-purpose socket class should be reference counted.
