> I'm attaching a test case that fails.
> I noticed that if I create a table with two column families, and start a 
> scanner on a row which only has an entry for one column family, the scanner 
> will skip ahead to the row name for which the other column family has an 
> entry.
> eg., if I insert rows so my table will look like this:
> {code}
> row - a:a - b:b
> aaa   a:1   nil
> bbb   a:2   b:2
> ccc   a:3   b:3
> {code}
> The scanner will tell me my table looks something like this:
> {code}
> row - a:a - b:b
> bbb   a:1   b:2
> bbb   a:2   b:3
> {code}
