If you ever feel the need to be truly maniacal, write a tool that randomly adds one exit() call in a code base for every 100k lines.  Make sure this call is protected and isn't executed when DEBUG mode is on or while testing. Bury the change in a 1000+ line commit.  Bonus points if you can find a function which is only called once with no arguments.  Add the exit call as a define flag in the build system :).
