Why 'unexplained'? 'persistent_id' is called from the Pickler instance
being used in ObjectWriter._dump(). It is called for each and every
single object reachable from the main object, due to the way Pickler
works (I believe). Maybe persistent_id can be analysed and optimized
for the most common cases?
