Here's a good function header given the following:
I wrote the below code

    def _run_in_thread(self, *args, **kwargs):
        reactor = getattr(self, reactor_name)
        sync = getattr(self, sync_name)
        threadpool = getattr(self, threadpool_name)
        original = getattr(sync, method_name)
        return deferToThreadPool(reactor, threadpool, preserve_context(original), *args, **kwargs)
    return _run_in_thread

What's a good function header?
