If I remember correctly it was just on the contrary,
AC was implemented first (version I recall was 0.67,
I haven't looked at a code of earlier versions except
some truly historical stuff like 0.11 or 0.15)
and later because of memory problems Edwin mentioned
at least a few times BM was added to resolve those
issues.
