Sometimes the best approach when something seems magical or extremely unexpected is to step away to the marker board and draw pictures and a “movie” storyboard of what’s going on, tallying up visually everything. Unilaterally using strong or weak references is not the answer. Often when I go through that exercise, without cutting corners or assuming stuff, a solution usually presents itself. -- Gary L.
