Would this work :(?)
1. Auto load all the non-lazy fields on ejbLoad().
2. Keep a boolean (initialized to false) indicating if
the media has been loaded.
3. When the media accessor function is called
(getImage()), if the boolean is false, load the image
and set the boolean to true. Then return the image.
As far as the passivation, I would ditch the image and
set the boolean false.
