Something interesting's happening in the Linux line on the graph right
at the right edge of the plotted region (20 threads).  Could you perhaps
run NetBSD-current against Linux again with the maximum number of threads
ramping up to 40, to see what the two curves look like as we head in
that direction?

Either we degrade a lot more gracefully than Linux under load, or there's
an artifact in the Linux graph.  The current plot makes it impossible to
tell which, though.
