How can I disable the new history feature in Python 3.4?

Since upgrading to Python 3.4, all interactive commands are logged to ~/.python_history. I don't want Python to create or write to this file. Creating a symlink to /dev/null does not work, Python removes the file and recreates it. The documentation suggests to delete the sys.__interactivehook__, but this also removes tab-completion. What should be done to disable writing this history file but still preserve tab-completion? Additional details: - Distro: Arch Linux x86_64 - readline 6.3-3 - python 3.4.0-2
