Okay, I hadn't thought of that. But is it really more of a problem for
processes than for ipc or inodes? It's true that processes can change
their context, but that would change the sid, and we've already
collected that data. The sid-to-context-string mapping will only
change on policy load. I see the argument for narrowing the window,
but I'd like to see audit pick one way and stick to it.
