A possible optimization in the generated code, but not sure if this would work. 
We have to check this. Code if from TAO/tests/IDL_Test. Placeholder because 
Jeff is busy with other things at this moment.

Then another issues, but this is something I don't know for
sure. Take the following code from anonymousC.cpp:
 
// TAO_IDL - Generated from
// be\be_visitor_operation/operation_cs.cpp:78
 
char * All_Anon::anon_bd_string_test::TestFunc (
    ACE_ENV_SINGLE_ARG_DECL
   )
   ACE_THROW_SPEC ((
     CORBA::SystemException
   ))
 {
   if (!this->is_evaluated ())
     {
       ACE_NESTED_CLASS (CORBA,
 Object)::tao_object_initialize (this);
     }
 
   if (this->the_TAO_anon_bd_string_test_Proxy_Broker_ == 0)
     {
       All_Anon_anon_bd_string_test_setup_collocation ();
     }

I wonder if the check for
the_TAO_anon_bd_string_test_Proxy_Broker_ could be done 
within the if check for !this->is_evaluated (). The 
is_evaluated is only called once, the 
the_TAO_anon_bd_string_test_Proxy_Broker_ is checked each 
time, but what if there is just no collocation possible, then 
this All_Anon_anon_bd_string_test_setup_collocation () is 
called each time again. When we move it within the if we just 
try to setup things once. I am not sure if this impacts 
other things.
