  In 1969 Harold Widom published his seminal paper, which gave a complete
description of orthogonal and Chebyshev polynomials on a system of smooth
Jordan curves. When there were Jordan arcs present the theory of orthogonal
polynomials turned out to be just the same, but for Chebyshev polynomials
Widom's approach proved only an upper estimate, which he conjectured to be the
correct asymptotic behavior. In this note we make some clarifications which
will show that the situation is more complicated.
