All .events files generate aggregated stateful notifications.  For
anyone to do anything, they'd have to remember the previous state to
identify what actually happened.  Being hierarchical, it'd of course
need to walk down when an event triggers.

And how do you do that in a raceless fashion?

Hmm... I'm having trouble imagining why this would be a problem.  How
would it race?

Thanks.
