Hi Ben, I see. i was mistakenly assuming that once a got a new set of offers (via Scheduler.resourceOffers) that the previous set of Offers would be automatically rescinded or essentially no longer valid for my framework to use.
Currently my Frameworks processes one set of offers at a time (without blocking the Scheduler), so this does not sound like a big concern for me at the moment unless I get into aggregating offers across multiple Scheduler.resourceOffer calls.
