We should always ensure that when we fix something, or when we add something, we don't change the current behavior of httpd in an unintended way. This rev is a great example of that. The clearing of those scoreboard slots is completely unrelated to the actual change itself.
Of course, the "blame" is shared because even if the patch does change something, it is up to all of us to review it, not just by running and testing the code, but actually *inspecting* the patch for what it does. The very fact that this change made it all the way thru the backport process to end up in 2.4.x is a reminder that we all need to stay vigilant.
