You can't find unreachable objects doing a reachability scan starting
from the root, so this doesn't matter.  Transactions are a tricky
problem; if you're trying to modify every instance of C, but someone
else is always modifying a C instance, you'll probably never be able
to commit.  You might have to modify instances in smaller batches and
commit after each batch, then.
