Timothy, Thanks for the suggestion. Creating a million keys within the same with-server is possible, without seeing the NoRouteToHostException. So, hitting with-server so many times in so short a time period is definitely a bad idea (duh).
So, I think there is a problem with how my larger program (not in the gist) is using the redis-clojure library. I'm still seeing intermitted problems with "Not able to read expected number or bytes" which might be related. I'll post here if it turns out that it's related. Also, thanks for the dotimes/doseq suggestion. I hadn't worried about it, since it was just a quick example. But, thanks for the tip.
