You can still call Unix.fork, and do threading the C way, although obviously it's not as convenient as real threading support.

Here's an interesting page discussing the current effort to develop a multicore runtime: https://github.com/ocamllabs/compiler-hacking/wiki/Multicore...

That's a good point, and one I hadn't thought of. I wonder what it would take to wrap Unix.fork into a threading library to make threads more convenient?

There are apparently some such libraries already. I haven't used any, but they seem to all use process-level threading; there's no lightweight threading library (like Lwt) that uses real threads. Actually, I'm wrong; turns out it is possible to delegate Lwt threads to system threads: http://ocsigen.org/lwt/api/Lwt_preemptive. This model doesn't seem to allow communication between them, however.
