There never is a problem with garbage collection.  DGD handles that, no
matter if the LWO structures are self-referential.

Yes.  It is a good idea to distribute a very large amount of data across
several persistent objects.

There are more reasons for partitioning your data.  Once multi-processor
support goes in, DGD will handle 100 threads which each make a modification
to one of 1000 persistent objects much more easily than 100 threads all
modifying the same object.
