Right, you might say that this trades one symbol for another. What I
meant was, we only have a few "active_cache_changed" and soon (TM) they
might all be "the_index.cache_changed" or "index->cache_changed" and the
macro could be retired. My understanding of the history is limited, but
I was under the impression that this was like a transition macro (albeit
a very old one!).
