I did because it was wrong.

Technically it was wrong but practically it was not. see: http://news.ycombinator.com/item?id=2606096

In particular: "I trust Redis-on-disk every day less." --antirez (author of redis)

In short, it's not the intended use-case and you damned well better know what you are doing.
