BTW, that is not a good way to tell if objects are being deleted.
Simply the act of adding a __del__ to an object can *cause* it to be
not collected, due to the way python's GC works. Luckily that was not
the case here. :) A better method to tell if objects are being
collected is to create a list of weakrefs (with callbacks to print a
message, say) to the objects.
