* Change all use of CML to STM: Overall, it looks like this change improved the code. There are still some need for cleanup after the bomb was thrown, but it does look like it will turn out positively. If CML put you off the track for hacking on Combinatorrent, you can now do it with STM!
That's interesting! Honestly, CML put me off. But that was by assumption only: with an Erlang background I am very aware of actor concurrency, but feared to miss Erlang's very loose coupling of processes, together with registering processes by name and fighting Haskell's precise typing. I bet CML has the solutions, but STM/shared memory feels much more natural outside Erlang.
* Introduce RTS benchmarks: See http://jlouis.github.com/combinatorrent where we plot SVG-based sparklines for various key RTS parameters over time (works best in Opera or Chrome). A slow-changing regression has a much harder time hiding now.
Interesting too, but the graphs are still way too small and have way too few data to be intuitive. I recommend the Chart library that is the foundation to the Criterion graphs as well. Astro
