 * connection to the mySQL-server takes time, you should use
 * database serverobjects in your MUD which constantly keep the
 * connection to the mySQL-server.
 *
 * hence we use this instead of letting each object have its own connection.
 *
 * Actually we aren't using this code at all, since psyced makes no 
 * operations by which it makes sense to use SQL rather than flat files.
