Do AAs allocate on removal?

Thanks for your quick answer. So the call to GC.free() breaks it. Seems 
easy to fix, just don't free and let the GC do its work. Whatever, I've 
solved my problems by nulling out the value and calling a cleanup 
routine before the next entry is added.

         private static void cleanObjects()
         {
             if (shouldCleanObjects) {
                 foreach (key, val; objects) {
                     if (!val) {
                     objects.remove( key);
                 }
             }
             shouldCleanObjects = false;
           }
         }

  Seems to work, but I'm not shure if it is save to remove entrys while 
iterating. Can't find any advise at this.
