We show that Kramers rate theory gives a straightforward, accurate estimate
of the closing time $\tau_c$ of a semiflexible polymer that is valid in cases
of physical interest. The calculation also reveals how the time scales of chain
relaxation and closing are intertwined, illuminating an apparent conflict
between two ways of calculating $\tau_c$ in the flexible limit.
