Close Stack Cleanup

It’s my understanding that I am unable to reference objects on a card of a stack in a preOpenStack handler. Referencing an object in the stack opens the stack triggering a race condition which continually triggers preOpenStack. That is from memory though.

Performing the clean up in preOpenStack makes it happen before the stack is visible, at least according to the dictionary.

My experience is that this is true.
