Forgive the confusion, but 19.10 of the manual *is* the answer to your question: it describes exactly what you have to do for multiple C threads which to make calls into the OCaml runtime. You need to use caml_c_thread_register/caml_c_thread_unregister and caml_release_runtime_system/caml_acquire_runtime_system. You don't need your own mutex - OCaml already has its own "master lock", as described.
