LISP systems work better when they are continually up-and-running. Take Emacs for example. Clojure systems aren't much different.
I prefer to think of lein more as a launch tool than a build tool. I don't think anyone has mentioned it on this thread yet, but lots of people are using Stuart Sierra's component workflow for precisely this reason - you can make changes and see the effects very quickly simply by typing (reset) into the REPL. See https://github.com/stuartsierra/component For a working example of incremental compilation, see http://modularity.org/templates/dashboard.html - it will recompile your ClojureScript and Less css files incrementally, and can do so because it can keep context between resets. It's possible to add 'test' components which will run your tests after every reset. I don't have any templates demonstrating that yet, but I have seen people do it.
