And even if it did, it wouldn't explain why threaded processes become unkillable. In any event removing KSE makes the problem go away. 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. -Kip > > > It is trivial to hit on sun4v.
