  We study the orientifold daughter of N=4 super Yang-Mills as a candidate
non-supersymmetric large N conformal field theory. In a theory with vanishing
single-trace beta functions that contains scalars in the adjoint
representation, conformal invariance might still be broken by renormalization
of double-trace terms to leading order at large N. In this note we perform a
diagrammatic analysis and argue that the orientifold daughter does not suffer
from double-trace running. This implies an exact large N equivalence between
this theory and a subsector of N=4 SYM.
