*
* As mySQL "limits" the number of connections to 100 and as every
* 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.
