Can you please explain why cleanup of secondary resources are not to be done, If there is specific memory like external hugepage backed mempool none of the callback will be called. Also releasing internal stack memory and heap of secondary is not cleaned.
Is there specific reason why you do not want to clean? If yes, can you please point to the right direction what is breaking?
