Thanks for the wrapper, that turned out to be the problem with 'user' namespace I was REPLing in (other namespaces were refreshed as expected).
While resolving this I also found out that :after option of refresh function is indeed useful (my server was re-created with older version of ring handler otherwise). I also found out out that instead of passing :after reference one can use ((ns-resolve 'namespace 'constructor)) to ensure that system constructor is of latest version.
