openConnection is called the first time your slave needs to access a 
given host. closeConnection is not called at all at the moment I 
believe. When your slave needs to connect to another site, 
openConnection is called again. This implies a 'closeConnection' but 
closeConnection is not called.

Only when the slave is reused for a connection to another host it gets 
closed at the moment. A timeout would be usefull here. (To be 
implemented)

Something like:
 error(  ERR_UNSUPPORTED_ACTION, "mkdir" );

See slavebase.cpp. There are default implementations which already 
return this. So you probably don't have to care about functions which 
you don't support.
