Lifehacker:

The app SlowQuitApps does exactly as its name implies. Now, instead of just tapping Command+Q to kill a program, you have to hold Command+Q for a second. A little circular countdown pops up on your screen, closing your app once it completes. That’s it.

This used to be a much more devastating issue but now it’s just an annoyance. Still, nice little utility to have (yes – I know you can just remap Command+Q).
