ah, none of the are -current, but the problem i saw has
been around for a long time (netbsd-6 at least?) so i'm
not sure it was broken by the same change, or perhaps
fixed by the same fixed.

it may be -- looking at a test machine, i see that wd0
does not detach at reboot, and simple reboot didn't make
that count go up (but i'm not near the machine with a
long history of this...)

i'll try to setup a test for this.
