We were facing some test cases that created huge amounts of Prolog terms and in the same time had a failure driven loop removing them at once again. Can our garbage collector deal with that? Tri-color can be used to identify old and new variables. We went on and implemented a variant of David Ungars generation scavenging. We could gain various benefits with a new gc_minor() routine, and the winner was a backtracking friendly heuristic when to call it or not.
