Modern OCaml multithreading is still a couple years away, the current (very promising) approach is still at the design/experimental stage.

Out of curiosity, what is it about smart contracts that makes multithreading so important? Why isn't multiprocessing enough? [edit: sorry, I mis-read your comment. You said that multithreading probably isn't a big deal for this problem.]

Modern OCaml multithreading is still a couple years away

It's been a couple of years away for the last 10 years.

I know, and I hate sharing "it's coming soon" stories for that reason. But the recent multicore progress-update does seem well conceived, and so personally I'm giving them the benefit of the doubt. :)

For the record, the current story is that they are merging some multicore things into 4.08, and it will only be available as an "experimental" feature. So even after it is in the compiler, it will be a couple more revisions before it is fully accepted.

Right, I linked to these summary notes in a different comment:

It doesn’t necessarily have to be that far out: https://twitter.com/kc_srk/status/994535108127404038?s=20

That would be very nice. I was basing my comments on these meeting notes [1], which seem a bit more conservative. (Multicore should be available experimentally in early 2019, but not ready for production use. I guess the next steps depend on how well those experiments pan out!)

Not for smart contracts, just as a language in general.
