+	    <p>Lock counting can now be fully toggled at runtime in
+	    the lock counting emulator (<c>-emu_type lcnt</c>).
+	    Everything is enabled by default to match the old
+	    behavior, but specific categories can be toggled at will
+	    with minimal runtime overhead when disabled. Refer to the
+	    documentation on <c>lcnt:rt_mask/1</c> for details.</p>
