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