---------------------------------------
i'd prefer to not publicly expose this method. doing so would IMO mean
compromising a core feature of JSR-170.
> Allow to disable referential integrity checking for workspace

> Some operations like clone, remove operating on huge subtree of nodes
> requires a lot of memory. To copy, clone, remove subtree all nodes are loaded
> into transient spaces. It allows such operations to be transactional, from
> other side it requires a lot of heap size and this memory size is directly
> dependent on the size of subtree (number of nodes). In result of this in some
> cases it is impossible to make such operations in one step. In our
> environment sometimes 1 GB of java heap is not enough to succesfully clone
> subtree from one workspace to another.
> You can always clone (copy, remove) tree in chunks, but if you have
> references between subtrees such approach fails. Possibilty of temporary
> disabling referential integrity checking for experienced JCR user could be
> very usefull then.
> Another use case is to allow to clone selected subtrees of the whole
> structure between worskpaces. In our application we need to clone only some
> selected subtrees from one workspace to another. But we can not do that
> because of existing references. We need to clone the whol estructure first,
> then remove all unwanted nodes, which is really time expensive and memory
> consuming.
