I made some updates to a production system on my test system. I had forgotten a major cron job in my updates when I committed to CVS. That wasn't a good idea because the changes I did make got put in production. Insert grumbles from everyone here. Since that happened, I won't be committing any unfinished work to CVS. I don't know how most people do that sort of thing, but I was a big fan of committing often.
Minus two points for me.
