I don't believe that the default constructor is called. I am 
pretty sure delete immediately deallocates the object, 
deregistering its memory from the gc.

In fact I am 99% sure no constructor is called after delete, it 
would cause problems for objects with no default constructor, or 
for system related stuff done in constructors, and I haven't seen 
anything like that in my X11 work in d.
