I went with the latter and it seems to work.  Thanks.  Next question:

Take a look at the following scenario:

  1. allocate object
  2. client does something with object
  3. deallocate object

I have created a port class with a custom clean routine.  I want the clean
routine to be called if the object are NOT deallocated in step 3 (for example, 
the client dies).  Is this possible - or do I have hold an internal state for
every port?
