Really?

   What is the "aq_parent" that was used when wrapping the object?

   It is context of the "IndexableObjectWrapper".
   The context of the indexable wrapped object does not change.

Where does the context come from used when "aq_acquire" acquisition
wrapped the "IndexableObjectWrapper"?


The best way around such problems would probably by to make
"IndexableObjectWrapper" a public class.
