How about dividing this call from object A to object B to two calls
to object B? First one would return at that point where B now calls A
and the second call would give the object B the results of the
call. Any parameters required by object A could be passed as the
result from the first call.
AMI/AMH  might provide another solution if they are available. Or
perhaps multiple servants for object A.
I prefer to avoid two-way calls with CORBA as much as possible. I
once tried those with C++ and ACE/TAO, and it seemed to be too much
trouble. I didn't try AMI/AMH or multiple servants though as I was
just learning CORBA basics.
