I'm nearly a week behind again and am trying to avoid thinking.

I've had a (n old) version of utrace in -mm for ages and it didn't
break anything.

I still don't think I've seen a really compelling reason for merging
it.  At least, I wouldn't be able to explain why we did it.  But
presumably there _are_ such reasons, because it was a lot of development work.

Someone please sell this to us.
