+
+      <p>A new thread target for &os; that is suitable for merging
+	upstream has been written and lightly tested.  However, it is not
+	yet available as an option in the port.  This thread target uses
+	<tt>ptrace(2)</tt> directly rather than <tt>libthread_db</tt> and
+	as such supports threads on all ABIs (such as &os;/i386 binaries
+	on &os;/amd64 and possibly Linux binaries, though that is not yet
+	tested).  It also requires less-invasive changes in the MD targets
+	in GDB compared to the <tt>libthread_db</tt>-based target.</p>
