It's kind of sad too. There are lots of use cases where I want fast datastores, and you know what, if the database goes down, who cares?
For example, I do lots of experiment logging to a mongodb. If the power goes out, and the data is lost who cares? The data was no longer valid or useful -- but if I slow down my writes for 'safety' I will be causing problems by introducing delay in ways that could cause conflict.
