By Alex:  bundle pm stores nodes + its properties + its list of child
nodes in a compact binary blob.

This means read a node will load all child reference/properties to
mem, I cannot see it could be improved significantly by bundle pm.
It's possible with other pm store if the child/properties are stored
separately.
