There's already some discussion on https://news.ycombinator.com/item?id=34013767

Am happy to answer questions people have on this one as well, there's also some other OCaml contributors lurking.

We merged that thread hither, but I think I got it backwards - that one was the earlier submission and also has the more substantive article. So I'm going to reverse this.

Hope we can get a merge of the threads.

But we’ve waited too long for multithreading to merge them now.

:)

Done now.
