OOO, even better, use the weakref standard method for doing it.

I haven't done extensive testing, but on those occasions where I've used 
the class I provided earlier, everything eventually got deleted.  It was 
likely a function of the object heirarchy and interaction in my tests 
and applications.  That is, not likely to be duplicated by any sane 
person *wink*.
