Stephen -

As far as I know, there's now way to do this without changing the oop.  There is no control over what oop you get when you create a new object.  I can think of only 3 ways to go:

1.  Write a primitive that does this.

2.  Figure some truly nasty way of doing this that will stop working as soon as the security team gets farther along with their work.

3.  Use become.  I know it takes time (3ms in a 20Mb image of mostly pointers on a 400MHz Mac), but you can also do many of them at once.
