In practice it is rarely a problem.  The static friction
of the ways combined with the cut being driven against
one extreme of the backlash removes the opportunity for
the movement to rattle around within the backlash slop.

In the case of drilling where the force being exerted does
not oppose the movement backlash, static friction present
in the ways is usually sufficient.  Otherwise if not you can
add an automated gib/ways jamb nut to lock the movement.
