For you, there might still be the stumbling block performance. My direct port of Lukas' STM [1] performs a bit better than the port of it on top of my abstractions. However, comparing to Clojure is not entirely fair, since Clojure only tracks explicit 'refs'. While we in Smalltalk do not have that concept, and need to track everything. Lukas originally did benchmarks also with Pier or Seaside or so, don't remember precisely. You might find something in [2]. Helvetia [3] includes also a port of the STM, so you might be able to get your hands on some benchmarks to see whether it is fast enough for you. Would be interested to hear whether it is fast enough in practice.
