	5	> If in a single transaction, the master deletes a record and then get_or_creates a similar record, under the new behavior the get_or_create would find the record in the slave db and fail to re-create it, leaving the record nonexistent, which violates the contract of get_or_create that the record should always exist afterwards. We need to do everything against the master here in order to ensure correctness.
