+        The threading model was changed when the newlock2 branch
+        was merged to NetBSD-current.  If you boot with a new
+        kernel (version 4.99.10), then you also need a new pthread
+        library (/usr/lib/libpthread.so.0.7).  If you boot with
+        an old kernel, then you need the old pthread library
+        (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
+        the pthread library in sync, old threaded applications should
+        continue to work with an old or new kernel.  Note that named(8)
+	is the only threaded application in the base system.
