[development] drupal.org caching too aggressive?

Recently I've posted comments on Drupal.org, and after pressing the submit button I've seen the original post, without a message and without my comment. If I refresh, the comment is there. But at least once I've gone back and resubmitted, because as a user it looks like my post was simply ignored. I suspect that I'm seeing a cached page after posting the comment (although I am logged in). Is this what's going on? Anyone else notice this? -Dave
