this is similar to ffmpeg - where it will receive the first ctrl-c -- and then continue to the next b frame and write out the end file metadata which makes a valid video file. on two CTRL-C's it is a sigkill and it exits immediatley.
If I have 12 transfers going and I want to cancel would be neat to hit CTRL-C or send a sighup to the PID and have it finish what its doing without having to loose out on 20GB transfers.
Ya?
