When DPRINTF() expands 'if (xxx) yyy' it all goes horribly wrong.
That's why I changed it to

This is wrong; you're reverting rmind's cleanup.

Can you prepare a patch that applies before rmind's cleanup? (Or just
one that applies on netbsd-6?)

Why pollute code with redundant #ifdefs?
Right, I missed the point that KASSERT contains #ifdef DIAGNOSTIC. I
will fix that tomorrow morning.
