The data comes from a C++ thread running a market data feed. I was planning to manage the memory-mapped file in the same thread and only notify OCaml when new data is available, after extending the memory mapping. It seems to be the simplest approach to me.
I also need to launch a C++ thread from OCaml and talk to it but that's probably a subject for a new mailing list thread.
Thanks, Joel
