Aha, I think I only saw your first commit, thanks.  Yes, that
looked more appropriate, but I would have preferred a proper
review to a commit-as-obvious (assuming that was the track when
nothing else was stated), since this was more than just target
gating or *trivial* missing predicates.

You may be on the right track judging from the commit log, and I
see my hunch about MOVE_RATIO wasn't far off either.  I guess I
should look into it too with rested eyes, but I'm happy with
this direction; not disabling the test for many targets.

Thanks for looking into it again.
