This is branched off https://github.com/FoundationDB/sql-layer-client-tools/pull/84 so that needs to go in before you'll even want to look at this.
The new option that this uses is in: https://github.com/FoundationDB/sql-layer/pull/1417
Not a big deal but you might like to know: `errorFile.deleteOnExit()` before the try block would eliminate the need for the finally.
