As far as that goes, I wonder whether the list-checking code hasn't
long since served its purpose.  Neil Conway put it in when he redid the
List API to help catch places that were using no-longer-supported hacks;
but it's been years since I've seen it catch anything.  I suggest that
we might want to either remove it, or enable it via something other than
USE_ASSERT_CHECKING (and not enable it by default).
