 Description   
(require '[clojure.core.async :as a])
(let [c (a/chan)]
  (a/onto-chan c (iterate inc 0))
  (while true
    (a/<!! c)))

onto-chan is holding on to the head of the input sequence as it is unfolded, resulting in an (eventual) OutOfMemoryError.

I've attached a diff showing changes I made to onto-chan that fixed the problem for me.
