Formerly, ZCatalog contained a subtransaction.commit (to free resources). As now subtransactions are deprecated, someone tried to emulated the commit by means of "savepoint" and forgot the "optimistic=True" parameter.

As a consequence large transactions modifying data in a non "savepoint" capable datamanager (e.g. via a relational database adapter) will fail with a TypeError as soon as they reach the subtransaction threshold of the catalog.
