    Call the given function with the given arguments in a worker process.

    If the ``cancellable`` option is enabled and the task waiting for its completion is
    cancelled, the worker process running it will be abruptly terminated using SIGKILL
    (or ``terminateProcess()`` on Windows).

    :param func: a callable
    :param args: positional arguments for the callable
    :param cancellable: ``True`` to allow cancellation of the operation while it's
        running
    :param limiter: capacity limiter to use to limit the total amount of processes
        running (if omitted, the default limiter is used)
    :return: an awaitable that yields the return value of the function.
