Clojurians Log v2

Sorry, me again. What would be Manifold's alternative to core.async/offer!? I thought @(manifold.stream/try-put! s x 0) is the one, but it doesn't exert backpressure if the stream buffer is full, as it just fills up the pending puts queue until it blows up. Is there a way to put into the stream's buffer avoiding the pending queue?
