We've done quite a bit of digging in this area, and one thing I noticed
was that the default for _cursor_obsolete_threshold was increased from 100
(11.2) to 1024 (12.1.0.2). _cursor_obsolete_threshold controls the number
of child cursors are kept for a given parent cursor before it's marked as
obsolete and aged out. To accommodate that new limit, they have
likely changed some things internally.
