A fair question.  What the example obscures is that spam is, itself, a 
subobject of a object that uses Persistent.  Or does that not matter?

A related issue is that I also want the subobjects to obtain/acquire 
settings from their containing object.  Seems the same trick to do one 
should do the other, but _p_changed won't do double duty here.
