771 //
772 // 1. Check to see if any rollback files exist for instances of the
773 // given class. If so, perform rollback
774 // 2. Create a rollback file for the instance file. The rollback file
775 // contains the original size of the instance file.
776 // 3. Create a rollback file for the index file. The rollback file is a
777 // copy of the instance file.
778 // 4. Update the instance file to perform the operation.
779 // 5. Update the index file to perform the operation.
780 // 6. Increment the free count in the index file if necessary, and
781 // perform reorganization if the limit is reached.
782 // 7. Delete the rollback files.
783 //
784 // The recoverability algorithm itself works as follows:
785 //
786 // 1. Delete the index file.
787 // 2. Rename the index rollback file to have the same name as the
788 // index file.
