- Fix a couple of edge cases while switching between collections. - Raise error if attempting to switch collections mid-transaction. - Add logic for re-entrancy with long-running transactions. - Revert to the prior collection if passing a block to #collection. - Add a predicate to tell if you're currently within a long-running transaction. - Add separate commit/rollback to long-running transactions.
