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