For now (could break anytime), the general solution requires at least
the following, in no particular order:

	- Remove the child from the previous parent's child list; the
	  delete child method ought to work.
	
	- Insert the child in the new parent; the insert method should do
	  it.
	
	- Make sure that the child's parent fiels points to the correct
	  parent.
	
	- Handle the constraint records.

This last is perhaps the most difficult.  You should run the constraint
destroy processing, then the constraint initialize processing.

Doing all of these things in a correct sequence constitutes the general
work-around.  Are you sure that you want to do this?
