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

    def lock_thread(tmpdir, file_path):
        with FileLock(file_path) as lock1:
            path = basename(lock1.lock_file_path)
            assert (tmpdir.join(path).exists() and tmpdir.join(path).isfile())
        assert (not tmpdir.join(path).exists())
    from threading import Thread
    package_name = 'conda_file_3'
    tmpfile = join(tmpdir.strpath, package_name)
    t = Thread(target=lock_thread, args=(tmpdir, tmpfile))
    with FileLock(tmpfile) as lock1:
        t.start()
        path = basename(lock1.lock_file_path)
        assert (tmpdir.join(path).exists() and tmpdir.join(path).isfile())
    t.join()
    assert (not tmpdir.join(path).exists())

What's a good function header?
