I still have a concern with this patch, the included test does not  
actually test the fix, it passes even without the changes in dl-fini.c.

I believe these two checks suffice to test the new functionality:
   - la_objclose should be called after la_activity(LA_ACT_DELETE) for  
the closed object's namespace. (Since dlclose is not used in this  
test, AFAICT la_objclose is only called during program termination.)
   - la_activity(LA_ACT_CONSISTENT) should be the last callback  
received for every namespace.
