When performing a scan in the shell, Ctrl-C will terminate both the scan and the entire shell. Seems bad.
Last I remember looking at this it was a limitation of JLine. That being said, it was over 12mos that I looked into it.
I made a rough attempt at this, and it's definitely much harder to fix in a reasonable way than I had thought as well. This ticket may be obviated by ACCUMULO-1045.
