Just wildly guessing here but since renderers need to update e.g. the
Render Region when values are changed in the scene, which sometimes

Arnold are making heavy use of some custom OnValueChanged events.
Maybe this could cause problems when used excessively and/or or with
deep hierarchies?
Can't speak for Arnold, but yes, VRay does rely heavily on
OnValueChanged. Hope this helps the dev folks at Autodesk
