I'm not quite sure about your specific case, but is it possible to
just move the try-catch outside of the recursive function?
Perhaps this is not possible for your specific case, but it seems like
a clean way to handle it, so I would try and massage the problem into
something that can be expressed like this.
Hope that's helpful

eg.
(defn foo [i]
(println i)
(if (zero? i)
(throw (RuntimeException. "Reached Zero."))
(recur (dec i))))
(defn outer-foo [i]
(try
(foo i)
(finally
(println "finished."))))
