Hi. In one of my projects I am using a sliding-buffer which will silently drop items when too many new ones are pushed. I'd like to be notified when this happens. Would you recommend rolling my own impl of Buffer and UnblockingBuffer based on https://github.com/clojure/core.async/blob/master/src/main/clojure/clojure/core/async/impl/buffers.clj#L53 plus the logging?
