AFAIK the general way to avoid these issues is to store/log not the
"data-diff" but the higher-level operation that caused this diff.
E.g. log something like "add X to tree" instead of recording which nodes
in the tree were modified in which way.  This way, the presence or
absence of cycles in the representation of the tree doesn't come into
the picture at all.
