Bug 979

Reported by Maxim Voronoy <M.Voronoy@telesenskscl.com.ua>. He reports
(on MSVC 6.0 and Win2K/NT) that this IDL file:

interface A
{
    void method_that_dii(in long a);
};

and this client code:


    A_imp a;
    A_ptr a_ptr = a->_this();
    CORBA::Request_var req = a_ptr->_request("method_that_dii");
    req->invoke();
    //there we never get :(


cause the client to hang and task manager to show growing memory
usage. I tried a similar example and got no hang but I did see the
leak. The spec does not require checking like this to be done, but
it would be nice to throw an exception. Must figure out how to 
check on the server side without penalizing performance.
