Note that I've done only very limited tests with current; I've done
most of my work on netbsd-4 (and then "backported" it to current;
but it was only a one-line change in kernel sources).
I'll try to get one of my systems up to current and see if I can
reproduce it. The fact that we can't run a current kernel on netbsd-4
because of the pthread issues makes it more difficult to test both ...
