Is it possible to avoid call to destructor for structs?

Actually no. Since when Foo (class that instantiates Bar) gets 
GCed, that is the point that I need to destroy the whole 
infrastructure around Bar, including its recounted GC. So I am Ok 
if destructor of Bar does not get called this one time since I am 
just going to delete the whole block of memory that I have 
allocated for placing the refcounted instances of Bar.
