I'm not sure what Gary was referring to.  I don't think there are any  
problems with writing.  OTOH, modified objects won't be removed from  
memory.  Perhaps that was what he was referring to.  As Gary  
mentioned, you can use savepoints to cause modified objects to be  
saved to disk and thus removed from memory.
