[omniORB] How can be interface destructors compiled to be virtual

Why do you want to do that?
The only reason to make a destructor virtual is so you can derive from
it, allocate a derived class object on the heap via new then delete
the object using a pointer to a base class object. Sequences are not
polymorphic in nature(*), so I can't imagine a scenario in which this
would be appropriate or desirable.
I personally think it is okay to derive from classes in order to
extend the functionality in a non-polymorphic manner without making
the destructor virtual. I know this is not a universally held point
of view. I recently came across this blog:
(*) I think you could design a polymorphic sequence class but I don't
believe CORBA sequences had that as a design goal.
