Honestly, for this kind of low-level stuff I always use the Apache
Commons libraries, <http://commons.apache.org/>, esp. the Lang and IO
components. They've got every imaginable stream function, all
carefully and efficiently implemented. But if you're determined to do
it in Clojure, loop/recur is the way, as James demonstrated.
