Oh, right -- sorry, I misunderstood you.  That's one way to avoid that 
conflict, but it might be better for the common case to do it the other 
way 'round.  Put the methods, if they are rarely called, in some 
namespace object (or even an E4X namespace).

I can give advice on this if you want to pursue it.

Ok, but if a user writes a bad onClose method, which stores a reference 
to the object being finalized anywhere live, watch out!  There are no 
safeguards in the JS engine to prevent very bad things from ensuing.
