Thanks. I misunderstood your (original, unedited) comment to refer to a golang goro (go func()), not clojure go macro. Yes - this seems to be a key difference

Thanks. I misunderstood your (original, unedited) comment to refer to a golang goro (go func()), not clojure go macro. Yes - this seems to be a key difference of golang's approach. The runtime+scheduler conspire to make a blocking goro much cheaper than an OS thread.
