    /** tests various aspects of database document "revenants"
     *
     *  Well, I do not really have a good term for this ... The point is, database documents are in real
     *  only *one* aspect of a more complex thing. The second aspect is a data source. Both, in some sense,
     *  just represent different views on the same thing. For a given database, there's at each time at most
     *  one data source, and at most one database document. Both have a independent life time, and are
     *  created when needed.
     *  In particular, a document can be closed (this is what happens when the last UI window displaying
     *  this document is closed), and then dies. Now when the other "view", the data source, still exists,
     *  the underlying document data is not discarded, but kept alive (else the data source would die
     *  just because the document dies, which is not desired). If the document is loaded, again, then
     *  it is re-created, using the data of its previous "incarnation".
     *
     *  This method here tests some of those aspects of a document which should survive the death of one
     *  instance and re-creation as a revenant.
