Hot exit by default

Hot exit is one of my favorite new features in Sublime Text 2. I'd like to see an option to make hot-exit the default behavior for Sublime when Sublime is exited, either via the titlebar "X" or Alt+F4.

The latter can already be done by editing one's .sublime-keymap file, but there doesn't seem to be a way to change to hot-exit behavior for regular application closing.
