// Added note for caching here because it was the CommentIDList that is the main problem.
// Note about memcaching:
// Main problem with this is when a new comment is posted. It will only
// have that current comment in the list, which, after calling
// PreloadDiscussionMedia, means it will be the only piece of data added
// to the cache, which prevents all the rest of the comments from loading
// their own attachments. Consider either adding to the cache when a new
// file is uploaded, or just getting a list of all comments for a discussion.
// This is why memcaching has been disabled for now. There are a couple
// ways to prevent this, but they all seem unnecessary.
