Hi
        And thanks for this PB tips!
        But it doesn't seems to work with odmg, in fact I saw ( comment in
source ) that RemovalAwareCollection are there to be used with PB
This will allow to use the PB api in way pretty close to ODMG persistent
collections!" ( dixit Thomas Mahler ).

Thanks again
