SQUID magnetic measurements of CdTe/Cd_{1-x}Mn_{x}Te, x ≃ 0.5, multi-layers with different CdMnTe layer thickness w reveal the persistence of the spin-glass irreversibilities down to ≃ 16 Å thin layers, i.e., well beyond the previously postulated 40 Å as a quasi-2D threshold. The freezing temperature T_{f} is found to be a monotonic function of w, and it obeys a scaling law T_{f} ∝ w^{a}, with a 0.8 similar to that for canonical spin-glasses. Magnetic properties of all studied structures are found to be independent of the orientation of the magnetic field.
