Uhhhmmm no it doesn't. And even if it did, it wouldn't explain why
threaded processes become unkillable. In any event removing KSE makes

I guess I'll just continue advocating for the removal of KSE after
libthr has proven itself. I've been pretty happy with nokse+libthr on
my desktop running the dtrace branch, so I think we're getting there.
