Now it all makes sense :)

I was right in my initial assumptions then (but probably unclear when exposing it).

Thanks a lot.

The _p_mtime attribute is really the unusual one among the _p_*  
attributes
in that accessing it will unghostify the instance (and this seems  
reasonable).

I guess that _p_serial attribute should be understood to mean the serial
number of the last loaded state.
