You'll have to explain it in more detail, if a file changes then the content has to be re-analyzed and the attribute updated to reflect that.

Nevermind, I realized what you meant. You mean the attribute might be wrong, but the index always reflects what the attributes are currently set to (wrong or not).

You're right, the index wouldn't be atomic in that sense.
