> It seems that the new bulk createOrUpdate() implementation in RDB is prone
> for the deadlocks. It isn't a bug in the Oak code, but rather something
> related to the database implementations. The bug can be observed if we have
> multiple simultaneous bulk updates and some of the rows repeat among them.
> The attached patch contains an unit test {{testConcurrentWithConflict}}
> presenting the issue.
