I argue that in large-N supersymmetric QCD infrared renormalons are absent in the conformal window, there is no need in conspiracy between the coefficient functions and the vacuum expectation values of at least some gluon operators - no factorials appear in the former and the latter vanish. Based on this conclusion, I conjecture that in supersymmetric gluodynamics (supersymmetric Yang-Mills theory without matter) at least the leading renormalon ambiguity disappears, which would be consistent with the fact that the gluon condensate vanishes in this theory, «GμνaGμνa»=0.
