Spec says:
--
The garbage collector is not guaranteed to run the destructor for 
all unreferenced objects. Furthermore, the order in which the 
garbage collector calls destructors for unreference objects is 
not specified. This means that when the garbage collector calls a 
destructor for an object of a class that has members that are 
references to garbage collected objects, those references may no 
longer be valid. >> This means that destructors cannot reference 
sub objects. <<
