It is proved that the contribution of self-dual twisted gauge configurations (torons) to the gluino condensate 〈λλ〉 in $N=1$ supersymmetric Yang-Mills theory remains finite in the thermodynamic limit. Using the richer vacuum structure of the theory, defined in a twisted box, the authors explain the constant value of the instanton contribution to the condensate 〈λλ(x)λλ(y)〉. The physical picture obtained is consistent with tr(-1)F and the effective-Lagrangian approach.
