Can you provide a the Python program you requested given the following:
Complete the below
def fork_processes(num_processes, max_restarts=100):

    ''''Starts multiple worker processes.
    If ``num_processes`` is None or <= 0, we detect the number of cores
    available on this machine and fork that number of child
    processes. If ``num_processes`` is given and > 0, we fork that
    specific number of sub-processes.
    Since we use processes and not threads, there is no shared memory
    between any server code.
    Note that multiple processes are not compatible with the autoreload
    module (or the debug=True option to `tornado.web.Application`).
    When using multiple processes, no IOLoops can be created or
    referenced until after the call to ``fork_processes``.
    In each child process, ``fork_processes`` returns its *task id*, a
    number between 0 and ``num_processes``.  Processes that exit
    abnormally (due to a signal or non-zero exit status) are restarted
    with the same id (up to ``max_restarts`` times).  In the parent
    process, ``fork_processes`` returns None if all child processes
    have exited normally, but will otherwise only exit by throwing an
    exception.'
