I'm surprised your unit tests let it get to such a state... ;)

How about something like this?

    retry, total_fail = False, False
    try:
        some_function()
    except SomeException:
        some_function2()
        some_function3()
        retry = True
    finally:
        if retry:
            try:
                some_function()
            except SomeException:
                total_fail = True

Using 'finally' seems more explicit about it being part of the
exception handling than using a loop construct.

Actually, this is even more direct:

    try:
        some_function()
    except SomeException:
        some_function2()
        some_function3()
        try:
            some_function()
        except SomeException:
            raise SomeError
