Query: Non-perturbative quark mass renormalization   We show that the renormalization factor relating the renormalization group
invariant quark masses to the bare quark masses computed in lattice QCD can be
determined non-perturbatively. The calculation is based on an extension of a
finite-size technique previously employed to compute the running coupling in
quenched QCD. As a by-product we obtain the $\Lambda$--parameter in this theory
with completely controlled errors.
