It works fine here and it even outputs progress when not started with -v :)

I _think_ it's still reading the informations of your file system in when
it's not showing any progress.

And yes, there is little chance that you will break something in Ctrl-C
as all dangerous operations are atomic to user space. But don't sue me if I'm 
wrong :)
