IDBTransactionBackedImpl instances can be accidentally deleted during calls to abort/commit. This happens because IDBTransactionBackedImpl invokes IDBTransactionCoordinator::didFinishTransaction(), which will release its reference to the IDBTransactionBackedImpl instance. If that was the last reference, the IDBTransactionBackedImpl instance is deleted and we crash.
