If you flush the PRHistoryPersistency the references should go. Unless

I don't think that there are any Smalltalk VMs left that do not

Keeping the relationship is intentional to be able to remove and
reinstall the tree somewhere else. I think the parent link is also
required to be able to restore a deleted page.
Well noted; thanks for the precisions!
So why do you think the parent should be nilled?
It seems that the memory space is never released, because even when later
the *max history* is reached in PRHistoryPersistency, #do: just removes from
its history collection the context that points to the "removed" (hidden?)
structure. So, if I understand well, the structure will not be garbage
collected due to the circular relationship between the parent and its
children?
